XRP Smart Contracts Hooks & EVM Sidechain
The XRPL is adding programmability without compromising what makes it great: speed and efficiency. Here's how Hooks and the EVM sidechain bring smart contracts to XRP.
Yes, XRP has smart contracts — but not like Ethereum. The XRP Ledger takes a two-pronged approach: Hooks are lightweight, on-chain programs for payment-adjacent logic, and the EVM sidechain provides full Ethereum-compatible smart contracts bridged to the XRPL. The main ledger also has powerful built-in features — escrow, DEX, AMM, payment channels, and native NFTs — that provide "smart" functionality without traditional contracts.
| Key Facts | |
|---|---|
| Smart Contract Approach | Hooks + EVM Sidechain |
| Hooks Language | C → WebAssembly |
| EVM Compatibility | Full Solidity support |
| Built-in Features | DEX, AMM, Escrow, NFTs |
| Payment Speed Impact | None (Hooks are lightweight) |
| EVM Bridge | Cross-chain asset bridge |
| Gas Token (EVM) | XRP |
| Design Philosophy | Payments first, programmability second |
XRP's Unique Approach to Smart Contracts
The XRPL's philosophy has always been payments first. Rather than trying to be a general-purpose computing platform like Ethereum, the XRPL adds programmability in ways that don't compromise its core strengths: 3-5 second settlement, near-zero fees, and 1,500+ TPS.
This means XRP uses a layered approach. The main chain stays fast and lean for payments. Hooks add lightweight logic directly on-chain. And complex smart contracts run on a separate EVM-compatible sidechain that bridges back to the main XRPL.
DEX, AMM, escrow, NFTs, payment channels — 'smart' features baked into the protocol.
Lightweight C/WASM programs that add conditional logic to transactions without bloating the ledger.
Full Ethereum compatibility on a separate chain, bridged to the XRPL for complex dApps.
XRPL Hooks: Lightweight On-Chain Logic
Hooks are small, efficient programs written in C that compile to WebAssembly (WASM) and attach to XRPL accounts. They execute automatically when certain transactions occur — like middleware that intercepts and processes payments.
Conditional payments
Hooks can enforce conditions before a payment goes through — like requiring a specific memo, minimum amount, or destination tag.
Automatic forwarding
Automatically split or forward incoming payments to multiple recipients — useful for payroll or revenue sharing.
Compliance checks
Run AML/KYC logic on transactions before they settle — critical for institutional adoption.
Rate limiting
Limit the frequency or amount of transactions from an account — useful for subscription models or spending controls.
Carbon credit integration
Automatically offset carbon for each transaction — an example of the creative possibilities.
Hooks are intentionally simpler and more constrained than Ethereum smart contracts. They can't create complex DeFi protocols with arbitrary logic, but they're fast, cheap, and safe — exactly what payment-adjacent logic needs. Think of Hooks as "transaction rules" rather than "programs."
The XRP EVM Sidechain
For developers who want full Ethereum-compatible smart contracts, the XRPL offers an EVM-compatible sidechain. This is a separate blockchain that:
Runs Solidity smart contracts
Deploy existing Ethereum smart contracts without modification. Any Solidity developer can build on it immediately.
Uses XRP for gas fees
Transaction fees on the EVM sidechain are paid in XRP, increasing demand for the native token.
Bridges to XRPL mainnet
A cross-chain bridge allows assets to move between the EVM sidechain and the main XRP Ledger.
Supports Ethereum tooling
MetaMask, Hardhat, Remix, and other Ethereum developer tools work out of the box.
Cheaper than Ethereum
Lower gas fees than Ethereum mainnet while maintaining full EVM compatibility.
Built-in Smart Features (No Contracts Needed)
Even without Hooks or the EVM sidechain, the XRPL has powerful built-in features that other blockchains need smart contracts to achieve:
Decentralized exchange built into the protocol. Trade any XRPL-issued token without a smart contract.
Provide liquidity and earn fees through the native AMM. No Uniswap-style contract needed.
Time-locked and condition-based escrow for conditional payments. Used by Ripple for XRP supply management.
Off-ledger payment channels for high-frequency micropayments. Settle thousands of payments with one on-chain transaction.
Native NFT minting, trading, and royalty enforcement. No ERC-721 contract needed.
Require multiple signatures for transactions — built-in multi-sig without a smart contract wallet.
