How Streamline handles money

A Streamline coin has a beneficiary written into it at launch. Traders buy and sell on a bonding curve. A fixed percentage of every trade is taken as a tax, split three ways, and the largest share leaves the chain entirely and arrives as gifted subs, a donation, or a sponsorship.

Nothing about that is automatic magic. A payout involves us converting SOL to dollars and spending it somewhere. The rest of this page says exactly how, per destination, including what each destination keeps.

Every coin uses the same curve, so a trader learns it once and it holds everywhere on the platform.

Once net buys reach 85 SOL the pool migrates and liquidity is locked permanently. Fees do not stop at graduation. Locked LP keeps earning, and that keeps flowing to the same vault the beneficiary is paid from.

The creator picks a tax between 1% and 3% when they launch. It applies to buys and sells alike and it never changes, from the first trade to long after graduation.

A creator can optionally buy some of their own coin in the same transaction as the launch. It cannot be front‑run, because the pool does not exist until that transaction lands, and it pays the same tax as any other trade. A dev buy is therefore the first money toward the beneficiary.

The rate is set on the config key rather than the pool, so coins sharing a rate share a config. That is an implementation detail with one visible consequence: the first coin at a given rate costs slightly more to launch than the ones after it.

Meteora takes 20% of every trading fee before anything reaches us. That is a cost of using the curve and nothing we can configure changes it. What is left splits three ways.

On chain there is only one account. The whole tax accrues to a single vault per coin, which the platform claims. All three shares above are then paid out of that vault and recorded against the coin that produced it.

Worked example, on $1,000 of volume through a coin taxed at 2%:

Volume rather than a single buy, because a fee is a percentage and one trade is too small to show anything once it is split four ways. Buys and sells both count.

The beneficiary share leaves the chain differently depending on what the coin points at. Each rail has its own conversion path, its own release rule, and its own cut taken by the destination before the recipient sees anything.

Between a fee and a person receiving something there are five steps.

1. 01Fees accrue in the pool's vault, in SOL, as people trade.
2. 02The platform claims the partner share out of the vault on chain.
3. 03Claimed SOL is converted to dollars and loaded onto a virtual card, or sent by bank transfer where the destination takes one.
4. 04The payout is spent at the destination, held first where the release rule says to hold.
5. 05The receipt is posted against the coin, linking both the on-chain claim and the third-party evidence.

Once a payout is releasable it goes out within 24 hours. Where a rail needs the recipient to claim, the vault waits 30 days. After that the money goes to holders instead, and no one, including us, can send it anywhere else.

Every payout carries two links: the on-chain claim that funded it, and evidence hosted by someone who is not us. A sub bomb shows in the channel gifter list. A GoFundMe donation shows on the campaign page. A Sponsors payment shows on the maintainer's page.

• We do not change a coin's beneficiary after launch. Nobody can, including us.
• We do not change a coin's tax after launch.
• We do not take unclaimed vaults. They go to holders after the claim window.
• We do not imply that a beneficiary endorses a coin. Anyone can launch for anyone, which is the point and also the risk.
• We do hold the creator's share, so it is an obligation we owe rather than something they can take without us. It is earmarked on every claim and shown against their coin.
