Consider upgrading ethersv5

[shanefontaine]

Consider pros and cons between:

• ethersv5
• ethersv6
• viem

If outcome is ethersv6 or viem, upgrade repo to use native BitInt.

Reference Converstaion

Some unorganized notes about an attempted ethersv5 -> ethersv6 migration:

• When converting BN to BigInt, consider searching for these in the repo:
  • .type (for checking bn)
  • .hex (for checking bn)
  • _isBigNumber oldbn
  • bignum
  • BN
  • Math methods
    • BigInt\((.*?)\)\. for all typecasted bigitnts that are then added
    • .floor
    • .add
      • Watch out for <set>.add()
    • .sub
    • .mul
    • .div
    • .gt(e)
    • .lt(e)
    • .pow
    • .eq
    • etc.
  • SDK methods need to be wrapped…
  • : BigNumber
  • ish ?
  • Can we do everything with bigint? how should we think about it?
    • Would require BigInt(Math.xxx()) and other primitives
    • Maybe that is where ish comes in?
  • Migrate the DB values from bn to bigint
• Remove
  • All 'ethers/lib/utils' are top level
  • providers.Provider
  • All @ethersproject should be gone
    • Remove these from package.json
• All utils as ethersUtils should be gone
• Explicit changes
  • StaticJsonRpcProvider → JsonRpcProvider (V6 does this by default: src)
  • extends Signer → extends AbstractSigner (Signer is now an interface and AbstractSigner replaced the class)

Happy to assist if the decision is Viem. :)
