One deposit, several companies.
Owning US equities from outside the US means a brokerage account most people cannot open. Stock strategy takes one deposit, splits it by weight across Coinbase's 13 tokenized equities on Base, and buys the whole basket in one confirmation where the wallet supports it.
What goes in#
ETH, USDC, cbBTC or BRZ, on Base. Base only, and deliberately: the equities live there, and every leg has to share a router for a single approval to be honest. A cross-chain deposit is a bridge with its own failure modes and belongs in its own screen rather than hidden inside this one.
How the split works#
- Weights are whole basis points summing to exactly
10,000. Integer arithmetic throughout — no floats, so no drift. - The remainder of the division lands on the largest leg, so the legs always add back to exactly the deposit. Nothing is invented and nothing is lost.
- At most
8legs. Past that the per-leg amount gets small enough that fees dominate the trade.
One approval, not one per stock#
The batch carries a single ERC-20 approval for the whole deposit, then one swap call per leg. If two legs quote through different routers the build is refused rather than approving one of them and leaving the others unspendable.
Execution goes through EIP-5792 wallet_sendCalls when the wallet reports atomic batching, and one call at a time when it does not. The panel says which you will get before you commit, because it asks the wallet on connect rather than finding out during the run.
A leg that cannot be routed
What it will not do#
- Guess a token's decimals. A leg whose scale could not be read returns no target at all — the same refusal the sell side makes, and for the same reason.
- Promise one confirmation before the wallet has said it can do that.
These tokens track the share; they are not the share, and their price is set by the pools that hold them. Stock Radar measures what each one actually costs to trade.
