For episode 495, Co-founder and CTO Jack Xu joins Brandon Zemp to talk about Sign, a company building smarter, more transparent systems for global token distribution and credential verification.
Sign’s flagship product TokenTable has risen to be the largest token distribution platform, securing more than $4 billion in airdrops and unlocks, and reaching 40 million users and investors. Its omni-chain attestation protocol, Sign Protocol, is connecting real-world credentials to on-chain addresses and has onboarded governments including Sierra Leone.
