Komodo DeFi Framework v2.5.0-beta

WalletConnect Integration and Major Wallet Enhancements

This release introduces major connectivity and wallet management upgrades, highlighted by the integration of WalletConnect v2 for EVM and Cosmos chains, enabling secure transaction signing with external wallets. It also delivers numerous enhancements to wallet security, HD wallet functionality, the P2P network, and the trading protocol, alongside various performance optimizations and bug fixes across the framework.

Release Notes

Features:

• WalletConnect Integration

  • Comprehensive support for WalletConnect v2 was implemented by @borngraced, enabling secure connection and transaction signing for EVM and Cosmos coins using external mobile and web wallets.
  Click to expand details

  • Secure External Signing: Users can activate EVM and Cosmos coins without exposing private keys to KDF, as all signing operations are delegated to the connected WalletConnect-compatible wallet.
  • New RPCs for Session Management:
    • wc_new_connection: Establishes a new WalletConnect session.
    • wc_get_sessions: Lists all active sessions.
    • wc_get_session: Retrieves details for a specific session.
    • wc_ping_session: Checks the status of a session.
    • wc_delete_session: Disconnects and removes a session.
  • Note: NFT and UTXO coins are not yet supported via WalletConnect.
  • Relevant PRs: #2223, #2485, #2508

---

Enhancements

Wallet Improvements:

• Wallet Deletion: A new delete_wallet RPC was introduced by @shamardy to securely remove wallets after password confirmation. The currently active wallet cannot be deleted. #2497
• HD Wallet Message Signing: Support for signing messages from any derived address in an HD wallet was implemented by @borngraced. #2432, #2474
• Z-Coin Balance Tracking: Unconfirmed z-coin notes are now correctly tracked to provide an accurate spendable balance and prevent transaction failures by @borngraced. #2331

Peer-to-Peer Network:

• Seed Node Configuration: Hardcoded seed node IP addresses were removed by @onur-ozkan to improve network maintainability and decentralization. KDF now requires explicit configuration via the seednodes field. #2439
• Expirable Pubkey Bans: The ability to temporarily ban misbehaving pubkeys for a configurable duration was introduced by @onur-ozkan. #2455

Trading Protocol & Orders:

• Minimum Trading Volume: The hardcoded minimum trading volume for BTC (0.00777) was removed by @onur-ozkan. This change standardizes the validation logic, applying a more consistent minimum trading volume of 0.0001 across all UTXO coins and significantly lowering the entry barrier for BTC trades. #2483

RPC and Protocol Improvements:

• Simplified RPC Payloads: The mmrpc field is no longer required for calling most modern (v2) RPC methods. The server, refactored by @onur-ozkan, now uses a unified handler that automatically checks both legacy and modern interfaces, simplifying client-side logic. The mmrpc field is only required to explicitly call a v2 method when a legacy (v1) method shares the same name. #2450
• IBC Channel Handling: The IBC channel handler was refactored by @onur-ozkan to use embedded channel data from the coins file instead of relying on external chain-registry parsing. This improves reliability and reduces external dependencies. #2298

Bug Fixes:

Click to expand

• Hardware Wallet:

  • A race condition during the initialization of Trezor-based hardware wallets was fixed by @mariocynicys. The fix ensures the correct account is loaded before fetching the enabled address, preventing startup errors. #2504

• UTXO:

  • The validation logic for P2PK (Pay-to-Public-Key) inputs was corrected by @mariocynicys. The fix ensures that the signature in the scriptSig is correctly verified against the expected public key, as the pubkey itself is not present in the script. #2408
  • An issue with UTXO transaction fee calculation was resolved by @dimxy. The fix restructures the transaction building algorithm to properly account for the change output and correctly calculate the minimum relay fee based on transaction size, resulting in more accurate fee estimation. #2316

• EVM / ERC20:

  • A bug in event streaming was fixed by @mariocynicys where ETH addresses were being truncated during serialization. This caused malformed data in Server-Sent Events (SSE). The fix ensures addresses are always serialized in their full format. #2440
  • An issue with ERC20 token identification was resolved by @laruh. The lookup logic now uses the platform ticker alongside the contract address, preventing conflicts between tokens with the same address on different EVM chains. #2445

• Peer-to-Peer Network:

  • The IP resolution logic for seed nodes was improved by @onur-ozkan to enhance connection reliability, failing only if no IPv4 address can be found. #2487

NB - Backwards compatibility breaking changes

⚡ API and Configuration Changes

• WalletConnect/EVM Coin Activation: The priv_key_policy field for EVM coin activation is no longer a string. It now requires an object with a type field (e.g., "priv_key_policy": { "type": "ContextPrivKey" }). WalletConnect activation uses { "type": "WalletConnect", ... }. #2223
• EVM Coin Configuration: EVM coin configurations in coins files must now include the chain_id inside the protocol_data object. The legacy top-level chain_id field is deprecated. #2425
• Seednode Configuration: All hardcoded seed nodes have been removed. KDF will no longer connect to the mainnet (netid 8762) by default. Users must provide a list of seed nodes in the seednodes configuration field to connect to the P2P network. #2439
• IBC/Cosmos: The ibc_chains and ibc_transfer_channels RPC endpoints have been removed. The ibc_source_channel field now requires numeric values only (e.g., 12 instead of channel-12) [#2298](https://github.com/KomodoPlatf...

  • A bug in Cosmos transaction history address parsing logic was fixed by @onur-ozkan #2245
• Order Management
  • Cancel order race condition was addressed using time-based cache by @shamardy #2232
• Legacy Swaps
  • A legacy swap issue was resolved by @laruh where taker spent maker payment transactions were sometimes incorrectly marked as successful when they were actually reverted or not confirmed, particularly in EVM-based swaps. #2199
    • Two new events were added: "MakerPaymentSpendConfirmed" and "MakerPaymentSpendConfirmFailed"
  • A fix was introduced by @shamardy where Takers don't need to confirm their own payment as they can wait for the spending of it straight away. #2249
    • This invalidates this fix #1442, a better solution will be introduced where taker rebroadcasts their transaction if it's not on the chain.
  • A fix was introduced by @shamardy for recover funds for takers when the swap was marked as unsuccessful due to the maker payment spend transaction not being confirmed. #2242
    • The required confirmations from coin config for taker/maker payment spend are now used instead of using 1 confirmation max. This is because some chains require more than 1 confirmation for finality, e.g. Polygon.
• Swap watchers
  • Taker fee validation retries was fixed by @shamardy to work the same way as for makers. #2263
• Coins Activation
  • EVM addresses are now displayed in full in iguana v2 activation response by @borngraced #2254

Komodo DeFi Framework v2.1.0-beta

Essential New Features: Trading Protocol Upgrade, HD Wallet, Event Streaming, and Seeds Management

This release introduces a range of significant features designed to enhance the framework’s capabilities. The trading protocol has been upgraded to boost the security and reliability of swaps. HD Wallets have been integrated to enhance privacy and streamline address management for both UTXO and EVM chains. Event Streaming has been implemented to provide clients with real-time balance updates, with more real-time events planned for future updates. Seed Management has been enhanced to ensure robust seed generation and storage. These features are complemented by advancements in the NFT feature, expanded chain support for Trezor, fee improvements, ARRR/Pirate support in browser environments, and updates to the Tendermint protocol that facilitate integration with external wallets.

Release Notes

Features:

• Trading Protocol Upgrade:

  • A major upgrade to the trading protocol (enabled with "use_trading_proto_v2": true) was implemented by @artemii235 in several PRs. This upgrade is currently available only for UTXO/UTXO swaps. All other swap types are not yet supported with this new protocol.
  Click to expand details

  • This upgrade introduces significant enhancements:
    • Immediate refund handling for taker payments, including DEX fee refunds, and subsequent immediate maker payment refunds, effectively solving maker/taker backout issues.
    • New RPCs: my_swap_status, my_recent_swaps, and active_swaps V2.
    • Upgraded swap data is also accessible through V1 RPCs.
    • Important note: Seednodes must be updated to support and rebroadcast new swap protocol messages.
  • Relevant PRs: #1927, #1958, #1980, #2015, #2046.

• HD Wallet:

  • HD wallet functionalities were fully implemented by @shamardy for UTXO and EVM coins, allowing users to enable the feature with "enable_hd": true. For Tendermint and Pirate coins, only a single address is supported, following the BIP32/39/44 standards.
  Click to expand details

  • This implementation simplifies the process of importing mnemonics from other wallets into the Komodo DeFi Framework (KDF), enabling users to retain their balances, transaction history, and more.
  • Users can now manage multiple addresses for UTXO and EVM coins, enhancing flexibility and control. The path_to_address parameter was added to coin activation requests to set the default account'/change/address_index path used for swaps. If not provided, the default path will be 0'/0/0.
  • HD withdrawals from any account'/change/address_index path were added for UTXO, EVM, Tendermint, and ARRR coins.
  • Address scanning for balances is supported through the scan_for_new_addresses RPC, and users can manage their HD wallet with new RPCs such as account_balance, get_new_address, and create_new_account.
  • These RPCs (scan_for_new_addresses, account_balance, get_new_address, and create_new_account) can be managed through the task manager using task::<rpc-name>::(init, cancel, status).
  • For full HD wallet functionalities, including balance scanning and withdrawals, use task manager-enabled methods like task::enable_eth::init, task::enable_qtum::init, task::enable_utxo::init, task::enable_erc20::init, and manage tasks through task::<rpc-name>::(init, cancel, status).
  • Task manager withdrawals are also supported using task::withdraw::init.
  • Relevant PRs: #1933, #1962.

• Event Streaming:

  • Streaming channels using Server-Sent Events (SSE) to continuously send data to clients were implemented by @onur-ozkan in several PRs. This feature supports various event types, including P2P network events, coin balance events, error events, and heartbeat events.
  Click to expand details

  • P2P network events: Streaming real-time updates about the network status.
  • Coin balance events: For UTXOs, EVM, ARRR/Pirate by @borngraced, and Tendermint Protocols, providing continuous balance updates.
  • Error events: Emitted when there's an error in generating an event, ensuring robust monitoring.
  • Heartbeat events: Periodic notifications about the health of the streaming channel.
  • For WebAssembly (Wasm), event streaming uses Shared Workers instead of SSE, enabling a more flexible and efficient event handling mechanism.
    • SharedWorker support was added, allowing any worker path in event_stream_configuration, with a default to event_streaming_worker.js.
    • To handle broadcasted messages from the client side, an event listener must be implemented within the client browser environment to capture and process these events as they are streamed.
  • To utilize this feature, the event_stream_configuration needs to be added to the KDF config before starting.
  • Relevant PRs: #1945, #1978, #2013, #2041, #2058, #2076, #2080.

• Seed Management:

  • Seed generation, encryption, and storage were implemented by @shamardy, introducing secure methods for seed handling, including strong encryption and key derivation techniques.
  Click to expand details

  • Introduced a new get_mnemonic API for retrieving mnemonics as plaintext or encrypted.
  • Added support for a wallet_name parameter in the configuration, enabling KDF to handle seed management.
    • If wallet_name is used, wallet_password must be provided, allowing for encrypted storage and retrieval of mnemonics.
    • If no mnemonic is provided, a new one is generated, encrypted, and stored.
    • Existing mnemonics can be imported and encrypted, or mnemonics can be imported in an encrypted format.
  • Introduced a global database for storing encrypted mnemonics and wallet names, separate from individual wallet-specific databases.
  • Seed management is fully integrated within KDF when wallet_name config parameter is used, bypassing the need for external mnemonic handling.
  • Relevant PRs: #2014, #1939.

NB - Backwards compatibility breaking changes

• The mm2 binaries have been renamed to kdf, with backward-compatible copies provided for mm2 naming. However, WASM binaries use the kdf naming only, which is a breaking change. #2126 by @shamardy
