Forest Web
Return one bounded current EVM fee-history snapshot for a fixed supported chain using SolidRPC public JSON-RPC. Forest reports recent base-fee and latest sampled-block priority-fee percentile evidence only; it does not estimate a caller transaction gas limit, simulate, sign or broadcast a transaction, access a wallet, choose a transaction fee for the caller or guarantee an optimal fee.
