NeXchange is a decentralized, intent-based cross-chain execution protocol. It allows users to swap and stake assets across Solana, Ethereum, and NEAR — staking into protocols such as Jito and Marinade on Solana or Lido and Ether.fi on Ethereum — directly from a single NEAR wallet. No bridging, no wallet switching, no friction.
Built as a public good for the NEAR ecosystem, NeXchange provides seamless, AI-optimized, and verifiable cross-chain functionality for users and developers.
NeXchange enables NEAR users to:
- Swap NEAR to SOL, ETH, USDC, and more via AI-optimized execution.
- Stake directly into Solana, Ethereum, and NEAR staking pools from a NEAR wallet.
- Interact across multiple ecosystems using a single wallet.
- Automate treasury and DAO operations with verifiable results (planned).
- Execute cross-chain DeFi actions such as lending, borrowing, and yield farming (planned).
All actions are powered by signed intents, which are interpreted and settled by a decentralized network of solver nodes.
NeXchange is a modular, open-source public good that prioritizes:
- Transparency — fully auditable, on-chain execution.
- Interoperability — seamless NEAR to Solana and EVM integration.
- Modularity — built to be extended and forked by the community.
- User Experience — no wallet switching and no cross-chain gas management.
- Intent Creation — a user signs an intent from their NEAR wallet (for example, swapping NEAR for SOL and staking it).
- AI Optimization — the intent is interpreted, the optimal route is selected, and execution safety is verified.
- Broadcast to Solvers — the request is broadcast to a decentralized network of solver nodes.
- Execution and Verification — the winning solver executes the transaction on the destination chain and provides verifiable proof.
- NEAR-First UX — all cross-chain interactions begin from NEAR.
- Intent-Based Execution — signed messages, combined with chain signatures, unlock cross-chain actions.
- AI-Powered Routing — best price, speed, and reliability without manual route selection.
- Non-Custodial and Secure — no bridges, no wrapped tokens, no central intermediaries.
The protocol is organized into four modules:
| Module | Description |
|---|---|
| Frontend | Next.js dApp: wallet connection, staking UI, intents panel, and documentation. |
| Intents Engine | Wraps the 1Click / defuse SDK for the deposit, quote, swap, and withdraw lifecycle. |
| Chain Signatures | chainsig.js adapters to derive and sign Solana and EVM transactions from a NEAR account. |
| Staking Protocols | Jito and Marinade (Solana); Lido and Ether.fi (Ethereum). |
| Chain | Protocols | Status |
|---|---|---|
| Solana | Jito (JitoSOL) | Live |
| Solana | Marinade (mSOL) | Planned |
| Ethereum | Lido (stETH), Ether.fi (eETH) | Planned |
| NEAR | Meta Pool, LiNEAR | Planned |
Live, on-chain proof of NeXchange's NEAR-to-staking flow:
| Protocol | Chain | Transaction |
|---|---|---|
| Ether.fi | Ethereum | 0x048d34e6...abf2006 |
| Jito | Solana | 4cM874RB...L4vuV4 |
