 ### 1) Asset Transfer (Native ↔ EVM)

 - Use the official Sei Dashboard to move assets between native (Keplr/Leap/Fin) and EVM (MetaMask/Compass etc.) addresses: [Sei Dashboard Transfer](https://dashboard.sei.io/evm-upgrade) or the Bridge tab at [Sei Dashboard Bridge](https://dashboard.sei.io/bridge).

@@ -68,7 +68,7 @@
 - You used Keplr or Leap before and want assets available via an EVM wallet going forward.
 - You need to access tokens on apps that now expect an EVM (0x) address.

 **Migrate (larger amounts):**
 
-- **Manual migration:** Bridge USDC.n via [Stargate](https://stargate.finance/?srcChain=sei&srcToken=0x3894085Ef7Ff0f0aeDf52E2A2704928d1Ec074F1) to an intermediary chain with CCTP v1 and v2 (e.g., Base), then use CCTP to burn/mint native USDC back to Sei.
-- Other useful bridging frontends: [CCTP Exchange](https://cctp.exchange/)
+USDC.n reached Sei over IBC from Noble, so larger balances are best migrated to native USDC by routing back through Noble — this avoids the slippage of a direct DEX swap.
+
+- IBC-transfer your USDC.n from Sei back to Noble, where it becomes native Noble USDC, then use Circle's CCTP to mint native USDC on Sei. [CCTP Exchange](https://cctp.exchange/) is a useful frontend for the CCTP leg.
+
+Complete this **before** the SIP-03 upgrade, while IBC routing through Noble is still available.
 
 **For DeFi suppliers of USDC.n (Yei, Takara Lend, etc.):**
 
 - Wind down and withdraw your positions **before** migrating to native USDC. Failure to do so before the SIP-03 upgrade may result in inability to access your supplied assets.
 
+### 3) Address Association (Seistream)
+
+[Seistream's SIP-03 migration page](https://seistream.app/migrate-sip03) links your EVM (`0x...`) and Cosmos (`sei1...`) addresses for the **native SEI token** in three guided steps. It is a community-built tool that streamlines the standard association flow.
+
+Address association is the one-time, on-chain step that links your `0x...` and `sei1...` addresses so a single key controls both. It must be completed **before** the SIP-03 upgrade — afterward, Cosmos (`sei1...`) interfaces stop working and addresses can no longer be associated. See [Account Linking](/learn/accounts) for how association works under the hood.
+
+What the tool does:
+
+1. **Connect wallet** — connect any EVM wallet with an injected provider (MetaMask, Keplr, Rabby, Compass, Tangem, Trust Wallet, OKX, and most others).
+2. **Gas + association** — cover the small amount of SEI needed for gas (Seistream provides a mainnet faucet to help), then submit the transaction that associates your `0x...` and `sei1...` addresses on-chain. Any outgoing EVM transaction registers the link automatically.
+3. **Transfer from Cosmos** — send your existing native SEI from the old Cosmos wallet to the linked `sei1...` address, where it becomes spendable from your EVM wallet.
+
+This is a streamlined alternative to the manual association flow in [Migrating a hardware or mnemonic-only wallet](#migrating-a-hardware-or-mnemonic-only-wallet).
+
+<Warning>
+Seistream handles association for the **native SEI token only**. For USDC, USDT, ATOM, WBTC, and other IBC-bridged assets, use the [IBC Asset Migration Table](#ibc-asset-migration-table). Seistream is a third-party tool; its inclusion here is not an endorsement, and you should do your own research before connecting a wallet.
+</Warning>
+
 ## Migrating a hardware or mnemonic-only wallet
 
 If your wallet can export a raw private key, the simplest path is to import that key into an EVM wallet. A private key is independent of coin type, so it reproduces the same `0x...` and `sei1...` addresses in any wallet, and no funds need to move.
@@ -109,6 +130,10 @@
 
 This works because every account has exactly one EVM (`0x...`) address and one Cosmos (`sei1...`) address, both derived from the same key. Funds sent to the new account's `sei1...` address are therefore spendable from the EVM wallet that holds its `0x...` address.
 
+<Tip>
+Prefer a guided flow? [Seistream's SIP-03 migration tool](https://seistream.app/migrate-sip03) walks through these same steps — connect an EVM wallet, cover gas, associate addresses, then transfer native SEI from the Cosmos side. See [Address Association (Seistream)](#3-address-association-seistream). It covers native SEI only; the manual steps below work for any wallet you control.

 - **Associate before sending.** Associating the new account before transferring ensures the funds arrive at the correct, immediately spendable address rather than a temporary holding address.
 - **Optional verification.** To confirm the paired `sei1...` address independently, call `getSeiAddr(0x...)` on the `addr` precompile. See [Query Linked Addresses](/learn/accounts#query-linked-addresses).

 ## FAQ

 ### I am a Keplr / Leap wallet user; do I need to do anything?

@@ -180,6 +205,6 @@
 **Do not confuse address linking with staking migration.** Even though `sei1...` and `0x...` addresses point to the same underlying account once associated, the chain can only recognize this link after explicit association. Without association, your staked SEI will not be accessible via EVM after the upgrade, and you will have no way to unbond or claim rewards.
 </Warning>

 ### I hold USDC.n (USDC via Noble) — what should I do?

 You must swap or migrate your USDC.n to native USDC before the SIP-03 deprecation of Cosmos, CosmWasm and IBC related functionality, slated for **June 15, 2026**. After the upgrade, USDC.n may become inaccessible or lose its value on Sei. See the [USDC on Sei](#2-usdc-on-sei) section above for swap and migration options, or read the full announcement: [Holders of USDC.n Need to Swap or Migrate](https://blog.sei.io/announcements/holders-of-usdcn-need-to-swap-or-migrate/).
