Using ethers.js 6.X with GoChain

[treeder]

Use this little wrapper around ethers.JsonRpcProvider and you should be good to go.

import { FeeData, getBigInt, resolveProperties } from "ethers"
import { JsonRpcProvider } from "ethers"

export class GoChainRpcProvider extends JsonRpcProvider {
  constructor(url) {
    super(url)
  }
  async getFeeData() {
    const network = await this.getNetwork()

    const getFeeDataFunc = async () => {
      const { _block, gasPrice, priorityFee } = await resolveProperties({
        _block: this.getBlock("latest", false),
        gasPrice: ((async () => {
          try {
            const value = await super._perform({ method: "getGasPrice" })
            return getBigInt(value, "%response")
          } catch (error) {
            console.log("ERROR:", error)
          }
          return null
        })()),
        priorityFee: ((async () => {
          return null
        })())
      })
      return new FeeData(gasPrice, null, null)
    }
    return await getFeeDataFunc()
  }
}
