USDC began as Circle and Coinbase’s shared Centre standard. A US$3.3 billion SVB exposure tested its bank-dependent redemption path in 2023; Circle later took sole control of issuance while reserve assurance, company audit and holder redemption remained distinct promises.
Chainlink grew because Sergey Nazarov and Steve Ellis kept narrowing one awkward question: who tells a smart contract what happened outside its chain? A 2017 oracle paper became live feeds, verifiable randomness, offchain reporting, cross-chain messaging and a programmable runtime. LINK pays and backs selected services, but the token does not elect every operator, govern every contract or turn service revenue into a holder dividend.
USDG pairs regulated one-dollar redemption with a partner network that shares distribution economics, while Paxos retains reserve, compliance and contract controls.
PayPal put a familiar checkout brand on a public-chain dollar in 2023, but Paxos issues PYUSD, manages its reserve and operates chain-specific supply and intervention controls. Its later spread across seven native networks turned a wallet feature into payment infrastructure while keeping redemption and rewards subject to separate rulebooks.
Frax USD (frxUSD) is the 2025 reserve-backed stablecoin at Ethereum `0xCAcd…6E29`. It is separate from Legacy Frax Dollar and from the FRAX governance token formerly called FXS; redemption depends on available custodian routes, caps, fees and eligibility rather than a universal claim on every reserve.
