MEE Node powers the MEE infrastrucutre - a novel approach to chain abstraction.

To learn more about the MEE Protocol, check out the short version of the protocol overview available in a form of ethresear.ch post or take a deep dive and read our whitepaper.

Chain Abstracted Address

MEE Node executes transaction on user's behalf while allowing the user to pay for fees in any token on any supported chain. Users can fetch their chain abstracted address by querying the MEE Node and providing their master EOA address as an input, as explained in the docs below. The received address is a smart account fully owned by the master EOA. The user can top up this account with assets on one chain, and use the assets to execute transactions on any other Klaster supported chain - gas abstraction. The user can also use this address to execute complex flows across multiple blockchain networks - requested by the dApp. To see the list of supported chains & tokens, every Klaster node exposes the /info endpoint.

Supertransactions (sTx)

MEE Nodes generate and execute sTx bundles - a series of one or more blockchain transactions on multiple blockchain networks. The dApp developer can define arbitrary flows on different chains and let the MEE network execute them while the user only has to signe once to approve the flow and see it being executed. In other words, using MEE - single-chain interaction & experience is converted to the multichain experience while retaining security and account ownership.

Quote

/quote endpoint is used to get the quote from MEE Node. The dApp developer provides the wanted series of steps to be executed to the Klaster Node and the MEE Node responds back with the generated quote (a fully built sTx bundle). The Klaster Node also commits to execute the quote in a specifc timeframe, with commitment hash being included in the sTx bundle.

Execute

/execute endpoint is used to execute the sTx bundle after the user has received the sTx bundle (including the commitment), and signed the quote with their master wallet.

Important notes when building an ERC20Permit quote:

notice the permit quote is fetched using a separate API endpoint (\"/quote-permit\")
\n
gas payment token must support ERC20Permit standard
\n
approval amount set in the ERC20Permit signature must be enough to cover for the full quote fee plus any other transfer made from the user's EOA to the SCA
\n
when building iTx steps - the developer can use EOA funds by calling \"transferFrom\" function and moving funds from the EOA to the SCA before using funds for other operations
\n
the amount of funds \"pullable\" by the SCA/developer is equal to the provided amount when signing an ERC20Permit message
\n
not all tokens have the standardized Permit interface functions: version() & name() , for those it's best to provide these values manually and not read them from the contract state since this info is a static data that never changes
\n

Fetches the \"multichain\" wallet address for the given EOA wallet.
