Pairs, loops and beyond
A deterministic solver searches the whole round at once, so a match can run through three, four or more wallets.
Now on BNB Chain
Someone Wants What You're Selling
Sama finds the wallets whose rebalances mirror yours, swaps the shares directly between you in scheduled rounds, and lets you choose what happens to anything left unmatched.
Built for bStocks on BNB Chain: tokenized shares and ETFs, with USDT as cash.
Nothing leaves your wallet until you sign off on the exact amounts.

Rebalancing alone is the expensive way.
At 2 pm one wallet trims NVDAB. At 3 pm another adds it. Each pays the pool's spread and price impact, and neither ever learns the other existed.

Mirror-image orders.
You sell the NVDAB another wallet is buying. With nowhere to meet, you both pay the pool for a trade you could have done with each other.
No pair matches

Three-way swaps nobody spots.
AAPLB to TSLAB, TSLAB to NVDAB, NVDAB to AAPLB. No two of these wallets fit together, yet all three do. On a DEX, each pays the full cost.

Plenty of holders own share tokens but no BNB for gas, so they can't even approve. Sama can cover that gas.

Prompts you can't read.
A raw signature request tells you nothing. Sama spells out the exact shares going out and coming in before your wallet ever opens.
See the gap at a glance.
Sama reads your balances straight from BNB Chain, compares them with your target, and tells you in dollars what it would take to close the gap.
A matching engine made for share tokens.
Each round, Sama gathers every signed rebalance, nets out what overlaps across all members, and settles the matched part in a single transaction. The unmatched part stays your call.
