do not change the value of these keys when you upgrade.

Update index block

Change from

[index]
darwinia = { endpoint = "https://subql.darwinia.network/subql-bridger-darwinia/" }
darwinia_evm = { endpoint = "https://thegraph.darwinia.network/ethv2/subgraphs/name/bridge-darwinia" }

to

[index]
substrate_chain = { endpoint = "https://subql.darwinia.network/subql-bridger-darwinia/" }
evm_chain         = { endpoint = "https://thegraph.darwinia.network/ethv2/subgraphs/name/bridge-darwinia" }

Update ethereum block

Create new block as name [beacon]

[beacon]
# Beacon chain api endpoint and api supplier
endpoint                  = "http://unstable.mainnet.beacon-api.nimbus.team"
api_supplier              = "Nimbus"

Remove [ethereum].endpoint and rename [ethereum].execution_layer_endpoint to [ethereum].endpoint

For Darwinia<>Ethereum

Update contract address in the config:

[darwinia_evm]
contract_address = "0xD2A37C4523542F2dFD7Cb792D2aeAd5c61C1bAAE"
execution_layer_contract_address = "0xeC3c9B4d3674B3D03fdf20b082A3C2c669075990"

And there are three beacon api supplier could be used by bridger:

Nimbus:

• http://unstable.mainnet.beacon-api.nimbus.team
• https://www.lightclientdata.org

Lodestar:

• https://lodestar-mainnet.chainsafe.io/
