Chains and Wallets
Solana plus three EVM chains, two wallets, one account: what lives where, what costs what, and why a position is invisible on the wrong chain.
Four chains
Solana is the home chain. Three EVM chains sit next to it, and they are not a separate product: the same Terminal, the same convert, the same agents.
| Chain | Chain id | Gas | Explorer | What it is for |
|---|---|---|---|---|
| Solana | native | SOL | solscan.io | Spot, swaps, tokenised stocks, staking, the perps venue |
| Robinhood Chain | 4663 | ETH | robinhoodchain.blockscout.com | Memecoins on an EVM L2 |
| Base | 8453 | ETH | basescan.org | Memecoins on an EVM L2 |
| Ethereum | 1 | ETH | etherscan.io | Memecoins and majors on mainnet |
Two wallets, one account
You hold one Solana wallet and one EVM wallet. The EVM address is the same on Robinhood Chain, Base and Ethereum, because that is how EVM addresses work.
What is not shared is the ledger. Balances, orders, fills and positions are kept per chain.
This is the single most common confusion on the platform. If a token you bought seems to have disappeared, you are almost always looking at the right wallet on the wrong chain. Switch the chain selector before anything else.
Gas is not the same everywhere
Robinhood Chain and Base are L2s: gas is cents, and it barely moves the economics of a small trade.
Ethereum mainnet is not an L2. A swap there costs dollars, not cents, and on a small ticket the fee is a meaningful share of what you put in. The app shows the fee as a percentage of the ticket on Ethereum for exactly that reason.
Low gas makes a bad token cheaper to buy, not less likely to go to zero. The chain decides your costs; the token decides your risk.
What works on which chain
| Solana | Robinhood | Base | Ethereum | |
|---|---|---|---|---|
| Terminal, buy and sell | yes | yes | yes | yes |
| Convert / bridge | yes | yes | yes | yes |
| Deposit and withdraw | yes | yes | yes | yes |
| Agents | yes | yes | yes | yes |
| Tokenised stocks, RWAs, pre-IPO | yes | no | no | no |
| Staking | yes | no | no | no |
| Perps DEX | yes | no | no | no |
| Whales board | yes | yes | yes | yes |
Perps, staking and tokenised equities are Solana-only because that is where the venue, the validators and the tokenised assets are.
Minimums and mechanics
- Minimum buy on an EVM chain: $5. Below that, gas and routing dominate the trade.
- A buy from a Solana balance is ONE order, not three steps you manage: the bridge leg, the gas top-up and the swap are sized and watched together, so the second leg cannot fail for being a few cents short.
- A sell lands in ETH on the chain you sold on and stays there, so the next buy is instant with no bridge. Getting it back to Solana is a separate, explicit decision, which is what stops a round trip of trades paying bridge costs twice.
Adding a chain
A chain is one entry in one registry: id, RPC, explorer, data source, cash tokens. Nothing else in the product hard-codes a chain. That is why Base and Ethereum arrived without a rebuild, and why the next one will too.
