The objective of this document is to provide a brief overview of how to integrate with the EVM-Compatible MAP Relay Chain. For teams that already support ETH, supporting the MAP Relay Chain is as straightforward as spinning up an MAP Relay Chain node (atlas) (which has the same API as go-ethereum) and populating MAP Relay Chain ID (22776) when constructing transactions.
you can get it from or .
from source code:
then start a node with the RPC service on the background,use ./build/bin/atlas -h get more details.
Please note that personal_ namespace is turned off by default. To turn it on, you need to pass the appropriate command line .
MAP Relay chain transactions are identical to standard EVM transactions with one exceptions::
For development purposes, MAP Relay Chain supports all the popular tooling for Ethereum,like as MetaMask and Remix,Truffle and Hardhat, so developers familiar with Ethereum and Solidity can feel right at home.
We are compatible with the improvement of Ethereum eip1559, and set the minimum base fee to 100GWei.
ps: MAP Relay Chain consensus provides fast and irreversible finality with 5 seconds. To query the most up-to-date finalized block, query any value (i.e. block, balance, state, etc.) with the latest parameter.
Interacting with the Atlas node is identical to interacting with . You can find the reference material for Atlas API .
you can use the and libs interacting with the atlas.
If you plan on extracting data from the Atlas into your own systems using golang, we recommend using our custom .
