from: Give or get a work reference that lives onchain →A former employer can sign a reference about you onchain from another country, in minutes, for a fraction of a cent. The Ethereum Attestation Service is free to use; you pay only network gas, tiny on Base.
from: I fled with no papers. Who will believe me? →
