Marcus Feld

Solana engineer, SolForger

Marcus builds the transaction-signing tooling behind SolForger's benches, from the SPL create flow to the Token-2022 tax extension. He has been writing Solana programs and web3 clients since the 2021 token boom, and spends most of his time in the weeds of the Token program, Metaplex metadata, and the quirks of getting a versioned transaction through a wallet on mobile. He writes the step-by-step guides so the people who use the tools understand exactly what they are signing.
