Avalanche has migrated to EIP-1559, and now supports Type-2 transactions. Polygon has also made the switch on their Mumbai testnet, so it's expected to go live on mainnet very soon.

This poses a problem for us, since we rely on Etherscan API for priority fee estimates (slow/average/fast) and keep track of the BASEFEE. This API supports Ethereum only at the moment, which means on other EVM networks users are over paying fees by a lot. Here's a user complaining about it: https://community.brave.com/t/adjust-fee-mechanism-calculation/320507.

$ curl -s https://mainnet.infura.io/v3/<infura project ID> -X POST -H "Content-Type: application/json" -d '{"id":1,"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest", false]}' | jq '.result.baseFeePerGas'
"0x239edbf0f5"

$ curl -s https://api.avax-test.network/ext/bc/C/rpc -X POST -H "Content-Type: application/json" -d '{"id":1,"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest", false]}' | jq '.result.baseFeePerGas'
"0x5d21dba00"

$ curl -s https://polygon-rpc.com -X POST -H "Content-Type: application/json" -d '{"id":1,"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["latest", false]}' | jq '.result.baseFeePerGas'
null  // coming soon

This issue proposes to implement a fee oracle independent of Etherscan API, using the eth_feeHistory RPC. Here's the reference implementation in ethereum-remote-client: https://github.com/brave/ethereum-remote-client/blob/master/app/scripts/controllers/network/eip1559FeeOracle.js. I have not researched the latest and greatest fee oracle out there, but this one used to work quite reliably.

feat(wallet): disable EIP-1559 on Polygon and Avalanche
d0e6bac 
Our current EIP-1559 gas oracle queries the Etherscan API, which only
supports Ethereum mainnet. As a result, priority fee estimations on
custom networks use results for Ethereum mainnet, which can either
result in transactions being stuck in the mempool forever, or in
over-payment of gas fees.

This commit will be reverted in brave/brave-browser#20469.
