Supported Blockchains

Warp Protocol v3 supports 11 blockchain networks, enabling flexible and powerful cross-chain interactions.

EVM Chains

Warps support all major EVM chains. Actions on these chains use standard abi signatures and wei for values.

Ethereum

• Identifier: ethereum
• Native Token: ETH (18 decimals)
• Explorer: etherscan.io

Base

• Identifier: base
• Native Token: ETH (18 decimals)
• Explorer: basescan.org

Arbitrum

• Identifier: arbitrum
• Native Token: ETH (18 decimals)
• Explorer: arbiscan.io

Polygon

• Identifier: polygon
• Native Token: POL (18 decimals)
• Explorer: polygonscan.com

Somnia

• Identifier: somnia
• Native Token: STT (18 decimals)

MultiversX Ecosystem

MultiversX

• Identifier: multiversx
• Native Token: EGLD (18 decimals)
• Address Format: erd1... (bech32)
• Explorer: explorer.multiversx.com
• Notes: High gas limits (millions) are standard. Token transfers use the transfers array property.

VibeChain (LightSpeed)

• Identifier: vibechain
• Native Token: VIBE
• Explorer: vibeox-explorer.multiversx.com
• Notes: LightSpeed chains are inscribed on MultiversX mainnet but execute on their own sub-networks.

Other Chains

Sui

• Identifier: sui
• Native Token: SUI (9 decimals / MIST)
• Address Format: 0x... (32 bytes hex)
• Explorer: suiscan.xyz

Solana

• Identifier: solana
• Native Token: SOL (9 decimals / lamports)
• Address Format: Base58
• Explorer: solscan.io

NEAR

• Identifier: near
• Native Token: NEAR (24 decimals / yoctoNEAR)
• Address Format: account.near

Fastset

• Identifier: fastset

Chain-Specific configurations

Gas Limit Guidelines

Different chains require different gas limits for similar operations.

Operation Type	EVM Chains	MultiversX
Simple transfer	21,000	50,000+
Token transfer	50,000 - 100,000	500,000+
Contract call	100,000+	6,000,000+
Complex DeFi	300,000+	20,000,000+

Address Formats

• EVM / Sui: 0x prefix (e.g. 0x123...)
• MultiversX: erd1 prefix (e.g. erd1...)
• Solana: Base58 string (e.g. H7b...)
• NEAR: Account ID (e.g. alice.near or 64-char hex)

Using Chain in Warps

Root-Level Default

Set the default chain for the entire Warp:

{
  "protocol": "warp:3.0.0",
  "chain": "ethereum",
  "name": "ETH: Stake",
  "actions": [...]
}

Per-Action Override

Override chain for specific actions:

{
  "chain": "ethereum",
  "actions": [
    {
      "type": "query",
      "chain": "base",
      "label": "Check Balance on Base"
    },
    {
      "type": "contract",
      "label": "Execute on Ethereum"
    }
  ]
}

Dynamic Chain Selection

Let users choose the chain:

{
  "actions": [
    {
      "type": "transfer",
      "label": "Send",
      "inputs": [
        {
          "name": "Network",
          "type": "string",
          "position": "chain",
          "source": "field",
          "options": {
            "ethereum": "Ethereum",
            "base": "Base",
            "arbitrum": "Arbitrum"
          }
        }
      ]
    }
  ]
}

Global Chain Variables

Use these globals to reference chain-specific URLs:

• - Chain's API endpoint
• - Chain's block explorer URL

{
  "type": "link",
  "label": "View on Explorer",
  "url": "{{CHAIN_EXPLORER}}/tx/{{TX_HASH}}"
}
