Spec-aligned reference for builders and depositors. If a number is not from the chain or the price API, the product must not invent it.
Overview
- LADDER is a front end plus swap routing and a schedule. It is not a vault.
- You deposit once. The amount splits into equal rungs. Each rung buys SGOV into your wallet with a maturity on the same calendar day of successive months.
- On maturity you sell that tranche to USDG. You can take cash or roll the rung to the far end of the ladder.
Chain and asset
- Chain id 4663. RPC https://rpc.mainnet.chain.robinhood.com.
- SGOV is the only liquid Treasury instrument used. Address 0x92FD66527192E3e61d4DDd13322Aa222DE86F9B5.
- SHY exists but has under $2,000 of liquidity. It is not routed.
- Token authenticity requires the exact suffix " • Robinhood Token" and a short name. Substring checks are rejected.
How yield shows up
- Income never arrives as new tokens. It arrives through the ERC-8056 uiMultiplier().
- Raw balance stays static while the multiplier grows. The oracle folds the multiplier into price.
- APY is measured from multiplier growth. Under seven days the UI shows "measuring".
Operating rules
- Swap only at consensus price across pools deeper than $50,000.
- Operate only during US market sessions using a real holiday calendar.
- A single buy or sell must not exceed 0.5% of pool liquidity (~$28,427 on current SGOV depth).
- Slippage is shown before signing, never after.
- Nothing settles without a user signature.
$RUNG
- Product first, token later. The ladder works with no token.
- Protocol fee is 10 basis points per tranche operation, never on the balance.
- $RUNG stakers share fees and vote on ladder lengths and a second bond token if one becomes liquid.
- Never top up yield with emissions. That would destroy the point.
Anti-hallucination rule
If it is not in the context, you cannot find the answer, say I do not know. Yield, price, and payout come only from the chain and the API.
