Summary: Peanut is a consumer-facing global payments app built around digital dollars, especially USDC, for cross-border peer-to-peer transfers, payment links, and local bank cash-out. Its official materials emphasize self-custodied ERC-4337 smart accounts, biometric passkeys, low-friction transfers without mandatory KYC for core flows, and cash-out rails across Latin America, which makes it better cataloged as a self-custodial global money app and remittance layer rather than as a simple wallet or generic crypto payment link tool.
What it does:
Lets users send and receive digital dollars globally through an app-based peer-to-peer payment flow
Supports payment links so funds can be sent to recipients before they have an account
Offers local bank cash-out and fiat conversion flows across Latin American corridors including Argentina, Brazil, Mexico, Colombia, Peru, and Bolivia
Uses self-custodied ERC-4337 smart accounts with biometric passkeys instead of seed-phrase-first wallet UX
Supports crypto deposits from exchanges and wallets, plus card spending and QR-payment features according to the project’s own product description
Maintains a public GitHub surface spanning smart contracts, SDK, API, and UI repos, which is a meaningful signal that the product is more than a closed mobile app shell
Key claims:
Peanut’s llms.txt says the product offers “instant global peer-to-peer payments in digital dollars” and explicitly highlights self-custodied accounts, payment links, and local bank cash-out
The llms-full.txt file says funds sit in ERC-4337 smart accounts, account access is secured by biometric passkeys, and core send/receive flows do not require KYC
The same llms-full.txt file says bank connections trigger a one-time identity check via Persona, while Peanut receives only a pass/fail result rather than storing user documents itself
Peanut’s support surface positions the product around verification, passkeys, payments, deposits, and account recovery, which reinforces that it is trying to abstract stablecoin infrastructure into a mainstream money app
The public GitHub organization lists contracts, SDK, API, and UI repos, and the contracts repo plus SDK repo show Peanut ships an actual protocol/tooling layer underneath the consumer app
The smart-contract repo references deployed contracts and a bug-bounty program, while the SDK repo describes the core function as sending tokens through cryptographically secure links
Whitepaper: No canonical Peanut whitepaper or litepaper surfaced in this pass. The clearest current source of truth is Peanut’s own llms.txt / llms-full.txt files, help center copy, and public GitHub organization plus contract/SDK repos; see ../whitepapers/peanut-primary-sources-2026-04-27.md.
