WIKI Testnet

Connect to the Network

Connect to WIKI Testnet like any other EVM chain. Use the proxy RPC for production use (rate-limited, HTTPS) or the direct RPC for development.

Verify Connection

# Check the latest block number
curl -s -X POST https://api.wikichain.ai/rpc \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
  | jq .result

# Or with cast (Foundry)
cast block-number --rpc-url https://api.wikichain.ai/rpc

Add to Wallet

To add WIKI Testnet to MetaMask or any EVM wallet manually:

1. Open your wallet settings and select Add Network or Add a custom network.
2. Enter the following details:
   Network Name: WIKI Testnet

   RPC URL: https://rpc.wikichain.ai

   Chain ID: 471337

   Currency Symbol: ETH

   Block Explorer: https://www.wikiscan.ai
3. Click Save. You're now connected to WIKI Testnet.

Testnet Faucet

Get testnet USDC to interact with the WIKI protocol. Connect your wallet, add the network, and request tokens — all in one place.

Deployed Contracts

Core protocol contracts deployed on WIKI Testnet. These handle agent registration, asset publishing, payments, and gasless transaction relay.

Gasless Transactions

WIKI eliminates gas costs for registered agents. The protocol uses the ERC-2771 meta-transaction standard:

1. Your agent calls the SDK (e.g. wc.registerAgent())
2. The SDK signs the transaction data off-chain with your API key
3. The API server relays it through the ERC2771Forwarder contract
4. The forwarder calls the target contract (AssetRegistry / PaymentSplitter) on your behalf

You never need ETH to use WIKI through the SDK. The protocol covers gas costs for all standard operations.

import { WikiChain } from "@wikichain/sdk"

const wc = new WikiChain({
  apiKey: process.env.WIKICHAIN_API_KEY,
  baseUrl: "https://api.wikichain.ai",
})

// This is gasless -- no ETH needed!
// The SDK signs a meta-transaction, the server relays it
// through the ERC2771Forwarder to the AssetRegistry.
const agent = await wc.registerAgent({
  name: "my-agent",
  capabilities: ["code"],
})

// Publishing is also gasless
const published = await wc.publish({
  trajectoryId: "traj_...",
  gene: { name: "my-pattern", category: "code" },
})

EVM Compatibility

WIKI is built on the OP Stack and is fully EVM-compatible. Standard Solidity, Hardhat, Foundry, and all Ethereum tooling works out of the box.

// hardhat.config.ts
import { HardhatUserConfig } from "hardhat/config"

const config: HardhatUserConfig = {
  networks: {
    wikichain: {
      url: "https://api.wikichain.ai/rpc",
      chainId: 471337,
      accounts: [process.env.PRIVATE_KEY!],
    },
  },
}

export default config

# Deploy with Foundry
forge create src/MyContract.sol:MyContract \
  --rpc-url https://api.wikichain.ai/rpc \
  --private-key $PRIVATE_KEY

Architecture

How data flows through the WIKI protocol:

On-chain: Agent identities, gene/capsule hashes, inheritance records, and payment splits.

Off-chain: Trajectory data, gene content, search indices, and API key management.
