NEAR Intents Integration

Cross-chain token swaps via 1Click REST API. Get a quote, API provides deposit addresses, you build the deposit transaction and receive the resulting token automatically.

Quick Start - Pick Your Path

| Use Case | Start Here | |----------|------------| | React App | react-swap-widget.md - Example showing the pattern | | Node.js / Script | server-example.md - Example showing the pattern | | API Reference | api-quote.md → api-tokens.md → api-status.md | | Chain-specific Deposits | deposit-{chain}.md |

Integration Flow

GET /v0/tokens → POST /v0/quote (dry) → POST /v0/quote (wet) → Deposit TX → POST /v0/deposit/submit → GET /v0/status

Rule Categories

| Priority | Category | Files | |----------|----------|-------| | 1 | Examples | react-swap-widget.md, server-example.md | | 2 | API | api-quote.md, api-tokens.md, api-status.md, api-deposit-submit.md | | 3 | Deposits | deposit-evm.md, deposit-solana.md, deposit-near.md, deposit-ton.md, deposit-tron.md, deposit-stellar.md | | 4 | React Hooks | react-hooks.md | | 5 | Advanced | intents-balance.md, passive-deposit.md |

Critical Knowledge

1. Use assetId from /v0/tokens - never construct manually
2. dry: true = preview only, dry: false = get deposit address (valid ~10 min)
3. Poll status until terminal: SUCCESS, FAILED, REFUNDED, INCOMPLETE_DEPOSIT
4. Chain-to-chain is default - depositType and recipientType default to chain endpoints

Index

1. Examples (HIGH)

• react-swap-widget - Minimum viable React swap implementation with wagmi
• server-example - Node.js script for server-side swaps

1. API Reference (CRITICAL)

• api-tokens - Fetch supported tokens, cache result
• api-quote - Get swap quote, dry=true for preview, dry=false for deposit address
• api-deposit-submit - Notify API after deposit to speed up processing
• api-status - Poll until terminal state (SUCCESS, FAILED, REFUNDED)
• api-any-input-withdrawals - Query withdrawals for ANY_INPUT quotes

1. Chain Deposits (HIGH)

• deposit-evm - Ethereum, Base, Arbitrum, Polygon, BSC transfers
• deposit-solana - Native SOL and SPL token transfers
• deposit-near - NEP-141 token transfers via wallet selector
• deposit-ton - Native TON transfers via TonConnect
• deposit-tron - Native TRX and TRC-20 transfers
• deposit-stellar - Stellar transfers (MEMO REQUIRED)

1. React Hooks (MEDIUM)

• react-hooks - Reusable hooks for tokens, quotes, status polling

1. Advanced (LOW)

• intents-balance - Hold balances in intents.near for faster swaps
• passive-deposit - QR code flow for manual transfers

1. References

• concepts - Swap lifecycle, statuses, CEX warning, authentication
