Gnosis

Gnosis Chain (Formerly the xDai Chain) provides stability, scalability and an extendable beacon chain framework.

Development on Gnosis Chain is straightforward for Ethereum developers as it is an EVM compatible chain. Smart contracts can be written and deployed in the same way as for Ethereum just by setting a different RPC endpoint.

Any contract that works on the Ethereum mainnet can be redeployed to the Gnosis chain. Transaction costs are minimized, and all fees and transactions are paid with a single token (xDai). Many tools supporting Ethereum development are compatible with Gnosis Chain.

Gnosis supports standard JSON RPC calls

Gnosis

web3 library

  • clientVersion

Returns the current client version.

Example request

curl https://rpc.ankr.com/gnosis \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"web3_clientVersion","params":[],"id":1}'

Example response

{"jsonrpc":"2.0","result":"OpenEthereum//v3.3.0-rc.15-stable-88eb7d325-20211104/x86_64-linux-gnu/rustc1.48.0","id":1}

net library

  • net_version

Returns the current network id.

Example request

  
  curl https://rpc.ankr.com/gnosis \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"net_version","params":[],"id":67}'

Example response

{"jsonrpc":"2.0","result":"100","id":67}

eth library

Example request

eth_estimateGas

Returns the gas price for the transaction in hex.


curl https://rpc.ankr.com/gnosis \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{
    "jsonrpc":"2.0",
    "method":"eth_estimateGas",
    "params":[{
    "from": "0x8D97689C9818892B700e27F316cc3E41e17fBeb9",
    "to": "0xd3CdA913deB6f67967B99D67aCDFa1712C293601",
    "value": "0x186a0"
    }],
    "id":1
}'

Example response

{"jsonrpc":"2.0","result":"0x5208","id":1}
