06 · $SYIELD token & fees Launching

$SYIELD

$SYIELD is the protocol token of StockYield. It is launched on a public bonding-curve launchpad rather than by the protocol itself, and its trading fees fund the three things the protocol needs to grow: onchain liquidity, infrastructure, and development.

  • Ticker SYIELD
  • Name StockYield
  • Chain Robinhood Chain (4663)
  • Pair ETH
  • Launch Public bonding curve → locked liquidity on graduation

6.1 What the token is — and is not

$SYIELD is a plain ERC-20 with no admin functions, no mint after launch, and no protocol permissions attached to holding it. It is the funding and coordination asset for StockYield; it is not required to use any product, and no product pays out in it.

  • Funds the protocol. Every trade in the $SYIELD pool pays a fee; the protocol's share is allocated by the fixed split in §6.3.
  • Not a claim on anything. $SYIELD does not entitle holders to revenue, dividends, PT/YT, basket positions, or governance over immutable contracts. Statements that it does are false.
  • Not a security token. It carries no rights against StockYield, its contributors, or Robinhood.
Risk

Bonding-curve tokens are volatile and can lose most or all of their value. Nothing here is investment advice. StockYield does not custody $SYIELD, cannot reverse trades, and cannot change the launchpad's fee mechanics.

6.2 Launch mechanics

The token is created through a public launchpad on Robinhood Chain. The launchpad mints supply into a bonding curve paired with ETH; price rises deterministically with net buys. When the curve accumulates its graduation threshold of ETH, the launchpad migrates the pool into a conventional AMM and locks the liquidity.

The exact launch fee, trade-fee percentage, graduation threshold and launch-window duration are displayed by the launchpad at creation time and are visible onchain; they are quoted here only as mechanics, not as fixed numbers, because they belong to the venue.

6.3 Fee flow and allocation

Every swap in the $SYIELD pool pays a trade fee. The launchpad retains its platform share; the remainder — the protocol's fee revenue — is allocated by a fixed three-way split. The split is defined on received revenue so it holds regardless of the venue's own take.

Infrastructure & yield40 %2 %Oracle attestation, keepers, RPC and indexing, and settlement capital for live series.

The "target as % of volume" column assumes a 5 % pool trade fee with the whole fee reaching the protocol. Where the venue retains part of the fee, the shares in the first column apply to what the protocol actually receives.

Transparency

Allocation is executed from the creator wallet named in Deployed contracts. Every transfer out of that wallet is public on Blockscout; there is no offchain treasury.

6.4 The liquidity engine

The liquidity engine is the 40 % bucket that turns fee revenue back into onchain depth. It is a policy, not a contract: revenue is deployed as protocol-owned liquidity in three places, in priority order.

  1. $SYIELD / ETH pool. Protocol-owned LP so that the token's own market does not depend on mercenary liquidity.
  2. Stock Token routes. Liquidity on the Uniswap routes the app uses for Stock Tokens, so splits and basket mints have executable depth.
  3. Basket-desk capital. Deposits into the sDESK vault, increasing the desk's capacity to take the other side of user baskets. See Synthetic basket desk.
Not a yield promise

Liquidity-engine deployments are protocol-owned positions. They do not pay $SYIELD holders, and their size depends entirely on realised fee revenue.

6.5 Relationship to protocol contracts

The repository also contains a native token and fee-hook design (StockYieldToken, a Uniswap v4 tax hook, and a launch bundle). Those contracts are not the launch path for $SYIELD and are not deployed. Any future migration of $SYIELD onto protocol-native fee routing would be announced with contract addresses in Deployed contracts before it takes effect; until then, the launchpad pool is the only fee source.
