Robinhood Chain for a Solana wallet holder: what you already have, what you need

13 September 2026. Facts about Robinhood Chain for someone who holds a Solana wallet today, collected from the chain's own documentation and dated. Written by a community member who held SABL until 13 September 2026 and holds none since; runs the independent Sable Observatory at sable.primecircle.cloud. Not run by Sable Network or by Robinhood. Nothing here is a recommendation to buy anything.

The team has said Sable moves to Robinhood Chain. Whatever shape that takes, a holder who wants to be there needs an address on that chain and a little ETH for gas. Most Solana holders already have the first and do not know it.

The chain, in five lines

What you already have: Phantom

Phantom has supported Robinhood Chain since 23 July 2026. If you hold SABL in Phantom, the same wallet already has an Ethereum-style address (0x, then 40 hex characters) that works on chain 4663. Phantom shows one address per chain family; the Ethereum-style one is the one that counts here. You did not create anything new for it and you never need a seed phrase to find it; Phantom's own help pages show where it is.

That matters for one of the shapes the move can take: a conversion that asks for a destination address on 4663 can take your own Phantom address, and the safest page design pre-fills it rather than asking you to type one.

If you use MetaMask

MetaMask does not list the chain by default. Add it by hand with the values from the chain's documentation page, docs.robinhood.com/chain/add-network-to-wallet:

Type the values from the documentation page yourself, not from a message or a screenshot. A wrong RPC shows you a wrong chain.

Gas: a little ETH on the chain

Every transaction on 4663 is paid in ETH held on 4663. The documented way in is the canonical Arbitrum bridge from Ethereum mainnet (docs.robinhood.com/chain/connecting): fast into the chain, and a withdrawal back to Ethereum waits out the challenge period, about a week on Arbitrum chains. Check the destination chain name twice before confirming. A few dollars of ETH cover many transactions at this chain's fees, and you do not need it until there is something to do there.

What normal looks like

What this page does not say

Nothing here says whether to buy the new token, when, or where. The address does not exist yet; when it does, the checker at sable.primecircle.cloud/#move shows it with its two sources.
