✨ Changelog

New Roles:

• SWITCHBOARD_DISABLER_ROLE - Socket

Limits:

• Removed precompile limits
• max payload limit: 24_500
• max txs in a request: 10
• supported max msg gas limit for each chain

Rename:

• DumpDecoder: PayloadHeaderDecoder
• allowPacket: allowPayload
• CallFromChainParams: TriggerParams

Fees updater:

• precompile fees: query, finalise, timeout and callback needs to be updated by watchers

Watcher:

• signs on sb address and chainSlug to avoid replay attack
• digest updated
• watcher need to transfer credits or natives based on the fees plug events

Transmitter:

• bid needs a uint256 instead of FeesData struct
• execute function inputs updated
• allowed tx retry on socket till deadline
• transmitter address can be addr(0)

Auction:

• auction manager pays for the setTimeout precompile whenever used

Library:

• use LibCall for all .call()
• separated watcher Id encode decode to WatcherIdUtils

Plugs:

• use app gateway id instead of address
• plugs can directly call the functions of app gateway using interface without encoding call
• fees needs to be handled by plugs, it is deducted from app gateway on evmx
• fees plug: removed native support. can deposit whitelisted tokens for credits and natives on evmx

App gateway:

• users need to whitelist app gateways in fees manager or send approval data to the app gateway when used first time, once whitelisted, fees will be automatically deducted per use
• take value from app gateway overrides
• fees change from struct to a uint256
• removed callFromChain, trigger can be done with original contract interface hence no need to encode decode call data

Bugs:

• last promise from a request could be misused
• buffer added to gas left check on socket

Fees:

• Credits are backed by stable and used for transmitter and watcher fees which can be claimed back onchain
• For doing txs on chain, EOA will need natives which can be gained by depositing on fees plug on chain and can be claimed back.
• All precompiles have a constant fees
• callbacks use a fee for constant max gas limit hardcoded in watcher
• transmitter fee is deducted once the request is executed onchain.
• users can deposit natives to have credits on evmx
• withdrawTo uses uint256 instead of FeesData struct
• Socket fees introduced, 0 for now, will be used in future (SocketFeeManager)
• on revert, fees is refunded
