Sui Wallet: Send, Swap and Bridge SUI With Low Gas Fees

Sui addresses, objects and coins

A Sui address is 0x followed by 64 hexadecimal characters, a 32-byte hash of your public key and its signature scheme. That length is the quickest way to tell it apart from an Ethereum-style address, which has 40 hex characters after 0x. In Keylo your Sui address and your EVM address are different, because they come from different keys and derivation paths.

Keylo derives your Sui key on m/44'/784'/0'/0'/0' with ed25519, the default path used by Slush and most other Sui wallets, so an imported phrase normally shows the same address. Your balance is made of coin objects: you might own several separate SUI coins that together add up to your total. Wallets merge and split these automatically when you send, so you rarely need to think about it.

Unlike some chains, Sui has no activation deposit or minimum balance for a new address. Anyone can send SUI or tokens to it straight away, and the objects simply become owned by your address. Sui also has human-readable SuiNS names, but Keylo does not resolve them, so ask for the full 0x address when someone gives you a name instead.

How to create a Sui wallet with Keylo

Moving from Slush or another Sui wallet? Import its 12- or 24-word phrase. If you used multiple accounts or a secp256k1 key in the old wallet, only the first ed25519 account will match Keylo's address, and anything else stays reachable in the original app.

1. 1

   Visit Keylo's sign-up page from a browser on mobile or desktop.

2. 2

   Create your account with name, email, phone and password, then confirm your email.

3. 3

   Your browser generates and encrypts a 12-word recovery phrase. Keylo stores only the encrypted blob and never sees the words.

4. 4

   Open Sui in your asset list. The 0x address shown there is labelled Sui, so you will not confuse it with your EVM address.

5. 5

   Write the phrase down: Settings shows it once you confirm your password. Keep the paper somewhere safe and offline.

How to receive SUI and tokens

Because Sui addresses and EVM addresses both start with 0x, it is easy to pick the wrong one on an exchange withdrawal page. A Sui withdrawal needs the 64-character address shown under Sui in Keylo; an EVM network needs the 40-character address. Most exchanges validate the length, but double-checking takes seconds.

1. 1

   Tap SUI, or whichever Sui token you expect, then Receive.

2. 2

   Copy the 64-character address or open its QR code; one address covers SUI and all Sui tokens.

3. 3

   Ask the sender to choose the Sui network. Exchanges usually list it as SUI or Sui, including for USDC.

4. 4

   Look in Activity, where incoming transfers usually appear within a second or two, with a Suiscan link.

How to send SUI

Sui transfers are final once executed, so the review screen is the place to catch mistakes. If you are sending a token rather than SUI, check its full type, not just its symbol, and make sure you still hold some SUI, because every transaction pays gas in SUI regardless of which coin it moves.

1. 1

   Choose SUI or another Sui token and press Send.

2. 2

   Paste the recipient's 64-character Sui address or scan its QR code.

3. 3

   Enter the amount, or tap Max to send everything except what gas needs.

4. 4

   Review the summary: recipient, exact amount and network fee in SUI.

5. 5

   Confirm. Keylo signs in your browser and the transfer is usually final in under a second.

Sui gas fees explained: computation, storage and rebates

Every Sui transaction pays two kinds of gas. Computation covers the work validators do and is priced in units multiplied by the gas price, which must be at least the epoch's reference gas price. Storage covers the bytes your transaction writes on chain, since Sui keeps a storage fund that pays validators to hold data over time.

Storage comes with a twist: when a transaction deletes or shrinks objects, you get back a storage rebate of 99% of the storage fee originally paid for them. A transaction that cleans up data can therefore cost very little net, or even return SUI. Simple transfers cost a small fraction of a SUI, and Keylo shows the total in the summary before you sign. Keylo adds no fee to a normal send.

Each transaction also carries a gas budget, the most it is allowed to spend, which wallets set automatically. If a transaction runs out of budget it fails, but it still pays for the work validators already did, and nothing else changes. Because the reference gas price is fixed for the whole epoch, fees on Sui are unusually predictable from one transaction to the next.

USDC and other tokens on Sui

Tokens on Sui are coin objects of a specific coin type, written as a package address, module and name, such as an address followed by ::usdc::USDC. Circle issues USDC natively on Sui, and many other tokens live there too. Keylo lists the tokens your address holds alongside SUI and lets you send them the same way.

The coin type is what identifies a token, not its name or logo. Scammers mint look-alike tokens with familiar symbols and send them to random addresses. Before accepting a token as payment, or swapping into one, compare its full coin type with the one published by the issuer or shown as verified on Suiscan. Older bridged versions of USDC also exist on Sui, and they are separate tokens from Circle's native USDC, so check which one an exchange or app expects.

Swap and bridge SUI

Keylo includes in-wallet swaps and bridges for Sui through LI.FI, which aggregates decentralized exchanges on Sui and audited bridges to other networks. You can swap SUI for USDC on Sui, or move value between Sui and chains such as Ethereum, Solana or Arbitrum. Every quote states which venues or bridges will be used, the expected and minimum output, and each fee, so nothing is hidden in the rate.

Swaps on Sui settle almost instantly. Bridges take longer because the other chain has to confirm too, and Keylo lets you track a bridge until it lands. Should a cross-chain route fail partway, the bridge protocol returns the funds to the wallet that sent them. See swap and bridge for how Keylo chooses routes.

Practise on Sui Testnet

Turn on Testnet mode in Settings and Keylo adds Sui Testnet, where SUI is free from the official faucet and has no value. It is a good place to try sending, watch gas and storage rebates in action, and get used to 64-character addresses. Testnet and mainnet addresses look identical, so always check the network label in Keylo before sharing an address or sending real funds.

Sui safety tips

• Ignore NFTs and coins you did not ask for. Spam objects on Sui often carry website links that lead to wallet-draining pages.
• Check coin types before trusting a token. A familiar symbol proves nothing.
• Never paste your 64-character Sui address into an EVM withdrawal, or your 40-character EVM address into a Sui one.
• Keep a small amount of SUI for gas so you can always move your tokens.
• Store your recovery phrase offline and turn on two-factor authentication. Keylo security covers each protection.
• No genuine support agent will ask for your phrase or password.
