injective-bridge

name: injective-bridge description: Bridge tokens to and from Injective using deBridge DLN (fast, cross-chain) or Peggy (Ethereum canonical bridge). Supports inbound bridges from Arbitrum, Ethereum, Base, Polygon, BSC, Avalanche, and Optimism into Injective, and outbound bridges from Injective to any deBridge-supported chain. Get quotes before executing. Requires the Injective MCP server to be connected. license: MIT metadata: author: InjectiveLabs version: "1.0.0"

Injective Bridge Skill

Overview

Move tokens cross-chain to/from Injective using two bridge protocols:

• deBridge DLN — fast (minutes), supports Arbitrum, Base, Ethereum, Polygon, BSC, Avalanche, Optimism
• Peggy — Injective's canonical Ethereum bridge (~30 min, decentralized)

Always get a quote first (bridge_debridge_quote / bridge_debridge_inbound_quote) before executing.

Outbound: Injective → External Chain

Step 1: Get a quote

bridge_debridge_quote
  address: inj1...         ← sender (Injective)
  srcTokenDenom: usdt      ← denom on Injective (symbol or full denom)
  amount: 50               ← human-readable amount
  dstChain: arbitrum       ← or: base, ethereum, polygon, bsc, avalanche, optimism
  dstTokenAddress: 0xaf88d065e77c8cc2239327c5edb3a432268e5831   ← USDC on Arbitrum
  recipient: 0x...         ← EVM address on destination chain

Step 2: Execute

bridge_debridge_send
  address: inj1...
  password: ****
  srcTokenDenom: usdt
  amount: 50
  dstChain: arbitrum
  dstTokenAddress: 0xaf88...
  recipient: 0x...

Inbound: External Chain → Injective

The Injective wallet's secp256k1 key signs on both chains (same private key works on EVM chains).

Step 1: Get a quote

bridge_debridge_inbound_quote
  srcChain: arbitrum       ← or chain ID: 42161
  srcTokenAddress: 0xaf88d065e77c8cc2239327c5edb3a432268e5831   ← USDC on Arbitrum
  amount: 50
  dstTokenAddress: 0x88f7f2b685f9692caf8c478f5badf09ee9b1cc13   ← USDT on Injective EVM
  recipient: inj1...       ← or 0x EVM address on Injective

Step 2: Execute (ERC20 approve + bridge tx on source chain)

bridge_debridge_inbound_send
  address: inj1...         ← Injective wallet (key used on source chain too)
  password: ****
  srcChain: arbitrum
  srcTokenAddress: 0xaf88...
  amount: 50
  dstTokenAddress: 0x88f7...
  recipient: inj1...

Ethereum Canonical Bridge (Peggy)

For withdrawals to Ethereum only (slower but decentralized):

bridge_withdraw_to_eth
  address: inj1...
  password: ****
  denom: peggy0xdac17f958d2ee523a2206206994597c13d831ec7   ← USDT denom on Injective
  amount: 100
  ethRecipient: 0x...

Peggy takes ~30 minutes. No quote needed; fees are fixed in INJ.

Chain Reference

Common Token Addresses

On Arbitrum:

• USDC: 0xaf88d065e77c8cc2239327c5edb3a432268e5831
• USDT: 0xfd086bc7cd5c481dcc9c85ebe478a1c0b69fcbb9

On Ethereum:

• USDC: 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48
• USDT: 0xdac17f958d2ee523a2206206994597c13d831ec7

On Injective EVM:

• USDT: 0x88f7f2b685f9692caf8c478f5badf09ee9b1cc13

Notes

• deBridge DLN settles in minutes. Quote includes fee breakdown and estimated receive amount.
• The inbound flow reuses the Injective wallet's private key on the source EVM chain — this works because Injective uses the same secp256k1 curve as Ethereum.
• If the source chain has no configured default RPC, provide rpcUrl explicitly.
• After an inbound bridge, tokens arrive on Injective EVM. Use subaccount_deposit to move them into the trading subaccount.
