How to Bridge Assets to SEI — Step-by-Step Tutorial

To bridge assets to SEI, you use a supported cross-chain bridge (such as IBC, LayerZero, Axelar, or Wormhole), choose the source network, connect your wallet, select the asset you want to transfer, and confirm the transaction.

Bridging lets you move tokens from other blockchains like Ethereum, Cosmos Hub, or Solana directly into the SEI ecosystem so you can stake, trade, or interact with SEI-based dApps.

Why Bridge to SEI?

SEI is a high-performance Layer-1 built for:

• ultra-fast trading

• real-time gaming

• low-fee payments

• EVM + Cosmos interoperability

Bridging lets you:

• fund your SEI wallet

• start staking SEI

• access SEI dApps

• use cross-chain liquidity

• deploy EVM contracts with ease

Supported Ways to Bridge Assets to SEI

Depending on your starting network, SEI supports multiple bridge options:

1. IBC (Cosmos-to-SEI transfers)

Best for:

• Cosmos Hub (ATOM)

• Osmosis (OSMO)

• Kujira, Injective, Juno, etc.

2. Axelar Bridge

Best for:

• Ethereum

• Coinbase Ethereum L2

• Avalanche

• Polygon

• BNB Chain

3. LayerZero

Best for:

• omnichain assets

• cross-chain stablecoins

4. Wormhole

Best for:

• Solana

• Ethereum

• BNB

• Polygon

This guide covers all methods, starting with the easiest one.

What You Need Before Bridging

You will need:

• A SEI-compatible wallet (Leap or Keplr recommended)

• A wallet on your source chain (MetaMask, Phantom, Keplr, etc.)

• The tokens you want to bridge

• A small amount of the source token for gas fees

Method 1: Bridge Assets to SEI Using IBC (Cosmos → SEI)

Fastest + cheapest method

Works for assets like:

• ATOM

• OSMO

• USDC (Cosmos)

• INJ

• KUJI

Step 1 — Install Leap or Keplr Wallet

Both support SEI + Cosmos IBC.

Step 2 — Select the Source Network

Example: Atom → SEI

Step 3 — Open the IBC Transfer Interface

Most wallets have a built-in IBC transfer tool:

• Click Transfer

• Select IBC Transfer

Step 4 — Choose Destination: SEI Network

Step 5 — Enter Amount & Confirm

IBC transfers are:

• fast (5–20 seconds)

• cheap (pennies)

• completely decentralized

After confirmation, your assets will appear on SEI automatically.

Method 2: Bridge to SEI with Axelar (Ethereum, Polygon, AVAX, BNB, etc.)

Best for:

• ETH

• USDC

• USDT

• Other ERC-20 tokens

Step 1 — Go to Axelar Bridge UI

(Example: satellite.money — depending on availability)

Step 2 — Connect Your Wallet

• MetaMask (for EVM chains)

• Leap or Keplr (for SEI)

Step 3 — Select Source Network

Example:
Ethereum → SEI

Step 4 — Choose Asset

Most users bridge:

• USDC

• ETH

• USDT

Step 5 — Enter Amount & Approve Transaction

Step 6 — Confirm the Bridge Transfer

Once sent, Axelar finalizes the transfer in:

• 2–10 minutes (Ethereum)

• 20–60 seconds (L2 or sidechains)

The asset will arrive as a wrapped Axelar token on SEI.Method 3: Bridge to SEI Using LayerZero

Best for:

• omnichain tokens

• OApp-based dApps

• advanced cross-chain routing

Steps:

1. Visit a dApp that uses LayerZero (e.g., Stargate, Router)

2. Connect MetaMask + SEI wallet

3. Select SEI as destination

4. Choose your token (USDC, USDT, ETH, etc.)

5. Approve → Confirm → Receive

LayerZero transfers are fast and gas-efficient.

Method 4: Bridge Assets from Solana to SEI (via Wormhole)

If you're starting from Solana:

• USDC (SPL)

• SOL

• JitoSOL

• Other SPL assets

Steps:

1. Open Wormhole Portal

2. Connect Phantom (Solana)

3. Connect Leap/Keplr (SEI)

4. Select SEI as destination

5. Choose asset (example: USDC-SPL)

6. Approve Solana TX

7. Confirm the final transfer

Wormhole will mint wrapped assets on SEI.

How to See Your Bridged Assets on SEI

Depending on the bridge, assets arrive as:

Native SEI tokens

(via IBC or native transfer)

Wrapped tokens

(via Axelar, LayerZero, Wormhole)

Wallets automatically detect:

• SEI

• USDC

• wETH

• wSOL

• other bridged tokens

If not, you can import the contract address in MetaMask-compatible SEI networks.

Common Issues & How to Fix Them

“My tokens didn’t arrive!”

• Check bridge explorer

• Confirm you selected the correct SEI chain

• Ensure your wallet is set to SEI EVM network

Assets not visible?

Import token manually using contract address.

Wrong network selected?

Contact the bridge support — many mis-sends can be recovered.

Bridging Fees — What to Expect

Bridge	Cost	Speed
IBC	Very low	5–20 sec
Axelar	Medium	1–10 min
LayerZero	Low–Medium	10–120 sec
Wormhole	Low–Medium	10–60 sec

Safety Tips

• Double-check the SEI network address

• Avoid bridging during chain congestion

• Use only official bridge UIs

• Beware of fake tokens — always verify

• Keep a small token balance for gas

Conclusion

Bridging to SEI is easy, fast, and inexpensive — especially with IBC and modern cross-chain protocols like Axelar, LayerZero, and Wormhole.
Whether you're moving funds from Cosmos, Ethereum, Solana, or another network, SEI provides multiple secure options to transfer assets and begin exploring its high-performance ecosystem.

In just a few minutes, you can bridge assets to SEI and start staking, trading, or using SEI-powered dApps.
