List of Peer to Peer & Remittance projects on Optimism (2026)

OKX Pay is a smart-account payment application built on a Layer 2 network that enables self-custodial stablecoin transfers without gas fees. Users split private key control between their device and OKX, using account abstraction and passkey or email-based recovery, and send stablecoins to recipients via phone numbers, email addresses, QR codes, or payment links. The platform also converts stablecoins to local currency at participating merchant point-of-sale terminals and applies deposits to low-risk onchain yield strategies, crediting rewards automatically. Users can bridge stablecoins in from several other blockchain networks to use within the app.

reply.cash is a peer-to-peer payment platform that lets users send stablecoins directly to mobile money accounts, bank accounts, and QR payment providers in emerging markets. Senders link a Solana wallet holding stablecoins, enter a recipient's phone number or bank details, and funds are automatically converted and settled on local rails without the recipient needing a crypto wallet. The platform supports cross-chain top-ups from multiple blockchains, consolidating value into a single balance for local payouts, and operates non-custodially throughout the transfer process.

Due Transfers is a cross-border money transfer service that moves funds using local payment methods across many countries. It allows instant transfers in stablecoins pegged to major fiat currencies, with settlement to local currency through rails such as bank transfers, mobile money, and crypto wallets. The service targets businesses and individuals sending payments to emerging and developed markets alike.

INBESTGO App is a self-custody cryptocurrency wallet and investment platform for individuals and businesses in Latin America. It lets users buy, sell, send, and receive a wide range of cryptocurrencies across multiple blockchains, fund accounts with local currency or dollars, and earn rewards on holdings through an integrated yield feature. A membership tier offers preferential withdrawal fees, and the app also manages linked crypto-funded payment cards. Businesses can access on and off-ramp services to convert stablecoins into local currency for payments.

EMCD Account is a custodial multi-asset platform account that stores, sends, receives, and swaps digital assets across multiple blockchain networks through a single login and dashboard. From the same account, users access savings under the Coinhold or Grow brand for daily-credited yield, peer-to-peer crypto-to-fiat trading, a centralized exchange for instant swaps, fiat on and off ramps, a crypto-backed lending product called OnLock, and a linked spending card. The account also provides delegated staking for select proof-of-stake assets, an index and real-world-asset investment offering marketed as Indesk or Portfolio, and tokenized U.S. equities and pre-IPO exposure branded xStocks, all settled through the same trading account. Every capability is reached through the shared web and mobile sign-in rather than a separate account or standalone application.

Pay(ID) is a universal stablecoin payment identifier that lets users receive any stablecoin from any supported blockchain using a single human-readable identifier instead of wallet addresses. It resolves incoming funds through user-defined routes that specify the destination currency, network, and wallet or account. The identifier is designed for both human and agentic payments, letting anyone pay a user by referencing their Pay(ID) rather than exchanging technical account details.

Koywe Payments is a payments infrastructure product that lets businesses collect and pay funds internationally across multiple Latin American markets and beyond. It processes pay-ins through payment links, hosted checkout, and in-person QR payments, and pay-outs to suppliers and other third parties, using local payment methods in each country. Companies, fintechs and payment service providers access the service through a single platform or API, receiving fee and exchange-rate quotes before confirming each transaction. The product also enables merchants to accept point-of-sale payments from foreign customers in the customer's local currency while settling in the merchant's own currency.

Request Network Protocol is a decentralized payment infrastructure that lets businesses and developers create, send, and accept crypto payment requests. It combines on-chain anchoring with distributed storage to generate verifiable invoices and payment links, track their settlement status, and route funds directly between wallets across multiple blockchain networks. Users access the system through a shared dashboard and API that support both collecting payments from customers and sending payouts to recipients, including cross-chain and crypto-to-fiat settlement options.

Peanut Protocol is a self-custodial peer-to-peer payments application for sending and receiving digital dollars across borders. Users deposit and withdraw funds using passkey authentication, then send money via simple links or QR codes, including local payment rails such as MercadoPago QR in Argentina and Pix in Brazil, with no local ID or bank account required. The app covers network fees on deposits and withdrawals and supports multiple stablecoins across several blockchain networks. Developers can integrate payment functionality into their own applications through an accompanying SDK and API.

Azza AI is a WhatsApp-based agent that lets users buy, sell, swap, and bridge crypto through chat commands. It converts crypto to local currency and back, enabling instant cashouts to bank accounts or mobile money, and lets users send crypto to contacts using a phone number instead of a wallet address. The agent also lets users track balances and manage assets without leaving WhatsApp, requiring a brief identity verification step before trading.

SRD Exchange is a decentralized trading platform that combines multi-venue futures trading, cross-chain token swaps, and peer-to-peer fiat conversion in one self-custody interface. It routes leveraged futures orders across multiple external liquidity venues so traders can compare leverage, fees, and pricing for the same pair without leaving the platform. Its swap feature moves tokens across several blockchains in a single transaction with fees covered by the platform, while its fiat module lets users in India trade USDT for INR directly with other users through bank transfer or cash deposit, secured by smart-contract escrow. All three functions are accessed through one wallet-based account rather than separate apps.

Loofta Pay is a non-custodial payment platform that lets users send crypto to anyone using only an email address or social handle instead of a wallet address. Recipients claim funds through a link and choose to hold them in one of many supported tokens or cash out directly to a bank account, while senders can optionally enable a shielded mode that hides the amount and counterparty from public view. The platform also generates shareable payment links and routes cross-chain payments through deposit addresses, letting a payer send whatever token they hold while the recipient receives exactly the asset and network they specified. Businesses can integrate the same rail through an SDK or hosted checkout to power payouts, gifts, payment links, and payroll within their own products. The platform supports transfers and routing across multiple blockchains and settlement tokens.

Kredete App is a financial platform enabling African immigrants to send money to their countries, build credit through international transfers, and access USD banking with FDIC-insured accounts. The system integrates stablecoin technology for secure cross-border payments while reporting transactions to credit bureaus for credit score improvement.

Charter Wallet is a non-custodial wallet that provides global payments, savings, and payroll functionality from a single account. Users send money across borders using a stablecoin balance, hold virtual USD and EUR accounts to receive funds locally, and settle payouts to supported banks in multiple regions. The wallet also lets users earn yield on idle balances and access early payroll disbursements from employers, alongside spending and expense tracking tools. It operates across multiple EVM-compatible blockchains.

Alfred Pay Platform is a cross-border payments infrastructure product that connects stablecoin rails to local banking systems across Latin America. It provides businesses with virtual local bank accounts, converts between stablecoins and local fiat currencies, and settles cross-border payments in near real time through a single API. Fintechs, crypto platforms, and trade and logistics companies use it to collect and disburse local payments and manage multi-currency operations without establishing local entities.
