L-EARN Tokenomics

L-EARN (Lock & Earn) is Coast's time-locked inflation participation program on PulseChain — part of positioning CST as a knowledge token: learn the rules, verify on-chain, then participate. You lock CST for a chosen duration, receive a duration multiplier on your share of the pool, and may receive allocations from the protocol's fixed 5% annual inflation schedule when inflation is funded to the vault.

This guide explains supply, locking, funding, exits, and risks. It is educational material, not investment advice.

L-EARN — short for Lock & Earn — is the Coast product at learn.0xcoast.com. Participants lock CST for fixed periods (90 days to 10 years) to receive a proportional share of protocol inflation distributions. Rewards come from CST's predetermined inflation schedule — not from Coast operating revenue.

The Play feature (skill game) is a separate product — this guide covers L-EARN (Lock & Earn) only.

Total CST supply evolves according to inflows and burns:

S(t+1) = S(t) + I + O + R − (Be + Boff)

• I — Inflation funded from the controller into the vault for distribution
• O — On-ramp: CST released from the conversion reserve (not minted by the vault)
• R — Referral mints (bounded annual budget, separate contract)
• Be — Early-exit burns (penalty and, on V2, forfeited inflation burned)
• Boff — Off-ramp burns where applicable in the live deployment

Protocol contracts do not offer retail mint(address) — inflation reaches lockers via funding and distribution.

Locks are created on-chain. Only the position owner (beneficiary) can end the lock — you may lock CST for another wallet (referrals, gifts).

Duration multipliers

Intermediate durations interpolate between these points. Weight used for inflation share:

weight = (principal × multiplier) / 10,000

The protocol targets 5% of current total CST supply per year for inflation (500 basis points — a fixed constant, not a governance knob). Allocations are proportional to your position weight vs total weighted stake while the lock is active and inflation is funded.

ASI (Annualized Share of Inflation, also shown on the dashboard) estimates your annualized share under current pool conditions. It is not a guaranteed return, bank APY, or interest rate.

Rewards use current total supply and current weighted stake — not values frozen at lock time. See Risks for implications.

The Arca is the vault's inflation funding and accounting layer. Locked user principal and inflation reserves are tracked separately in contract state even though CST is physically pooled in the vault. Inflation must be funded before it can be distributed — realized rewards can fall short of the formula if funding lags.

The inflation controller holds a reserve and enforces epoch requirements (~5% of supply per distribution cycle). On-chain readouts show balances, cumulative funded and distributed amounts, and funding coverage.

Maturity

After the lock end time, the owner may claim inflation and withdraw principal when eligible.

Early exit

Early exit is always allowed but penalized. Penalty scales with remaining time:

penalty = principal × (timeRemaining / totalDuration)

The penalty is burned (reduces circulating supply). On V2, forfeited inflation from the position may also be burned. Penalties are not redistributed to other lockers (unlike HEX penalty flows).

Production V2: new locks use CST you already hold. The live app pins lock creation to CST-only on the V2 vault.

Where stablecoin on-ramp is enabled, conversion draws CST from the conversion reserve — it does not mint at lock time. A 2.5% conversion bonus applies to the dollar value before the CST amount is computed. An empty reserve reverts the transaction.

That drawdown is the O term in the supply equation (reserve depletion, not vault mint).

The referral program allocates up to 500,000 CST per year for referral bonuses when new locks use valid codes. This is a bounded R term in the supply equation — separate from inflation funded to lockers.

Referral minting is not the same as inflation participation; the annual budget can be exhausted for the year.

• Funding risk: Inflation owed vs inflation funded — cadence and operator discipline matter.
• Pool composition: Rewards use live pool totals; new locks dilute share; exits concentrate share.
• Current-supply inflation: 5% is applied to supply at calculation time, not supply at lock time.
• Concentration: Large lockers dominate weighted stake without anti-whale mechanics.
• Owner keys: Vault owner can manage stablecoin lists, conversion reserve withdrawals, and accumulated stables; controller owner can withdraw excess reserve.
• Smart contract risk: Standard DeFi assumptions; verify live deployment before relying on new functions.
