64.1.0

Changed

• Add fee limit passthrough for Tron snap fee computation (#7426)

Fixed

• Update gas calculation logic to use the priority fee provided by the gas-api and stop adding the base fee (#7403, #7406)

64.0.0

Added

• Port fetchTokens and type SwapsToken from @metamask/swaps-controller and export them to allow deprecating swaps-controller while still supporting downstream consumers (#7278)
• Handle edge case in which approvals fail if an EVM account has an insufficient non-zero USDT allowance on mainnet (#7228)
  • Set quoteRequest resetApproval parameter by calculating the wallet's USDT allowance on mainnet for the swap or bridge spender
  • When a valid quote is received, append the resetApproval trade data to set the wallet's USDT allowance to 0
  • Include the resetApproval tx in network fee calculations

Changed

• BREAKING: Remove SWAPS_TESTNET_CHAIN_ID export and use CHAIN_IDS.LOCALHOST instead (#7278)
• Bump @metamask/network-controller from ^26.0.0 to ^27.0.0 (#7258)
• Bump @metamask/transaction-controller from ^62.3.0 to ^62.4.0 (#7257, #7289)
• Bump @metamask/assets-controllers from ^92.0.0 to ^93.0.0 (#7291)

Removed

• BREAKING Remove public getBridgeERC20Allowance action to prevent consumers from using it. This handler is only applicable to Swap and Bridge txs involving USDT on mainnet (#7228)

Fixed

• BREAKING: Add usd_amount_source to QuotesRequested event properties. Clients will need to add this value to the quoteRequest context (#7294)
• Add missing MON (Monad) and SEI (Sei) to integer chain IDs (#7252)

63.2.0

Changed

• Update stopPollingForQuotes to accept metrics context for the QuotesReceived event. If context is provided and quotes are still loading when the handler is called, the Unified SwapBridge Quotes Received is published before the poll is cancelled (#7242)

63.1.0

Added

• Port the following constants from SwapsController and export them: SWAPS_TESTNET_CHAIN_ID, SWAPS_CONTRACT_ADDRESSES, SWAPS_WRAPPED_TOKENS_ADDRESSES, ALLOWED_CONTRACT_ADDRESSES (#7233)
• Port the following utils from SwapsController and export them: isValidSwapsContractAddress, getSwapsContractAddress (#7233)

Changed

• Move peer dependencies for controller and service packages to direct dependencies (#7209, #7220, #7236)
  • The dependencies moved are:
    • @metamask/accounts-controller (^35.0.0)
    • @metamask/assets-controllers (^91.0.0)
    • @metamask/network-controller (^26.0.0)
    • @metamask/remote-feature-flag-controller (^2.0.1)
    • @metamask/snaps-controllers (^14.0.0)
    • @metamask/transaction-controller (^62.3.0)
  • In clients, it is now possible for multiple versions of these packages to exist in the dependency tree.
    • For example, this scenario would be valid: a client relies on @metamask/controller-a 1.0.0 and @metamask/controller-b 1.0.0, and @metamask/controller-b depends on @metamask/controller-a 1.1.0.
  • Note, however, that the versions specified in the client's package.json always "win", and you are expected to keep them up to date so as not to break controller and service intercommunication.

Fixed

• Update quotesLoadingStatus to "LOADING" if a balance fetch is needed before fetching quotes ((https://github.com/MetaMask/core/pull/7227)[#7227])
• Wait for async SSE message handlers before updating quotesLoadingStatus to prevent clients from displaying "No quotes" warnings ((https://github.com/MetaMask/core/pull/7227)[#7227])
