Staker Incentives

Stakers (delegators) earn two types of rewards on Tangle:

Service fee revenue from blueprint services they help secure (paid in the service’s payment token).
Optional TNT incentives for delegating assets (pre-funded by governance).

How You Participate

Deposit supported assets into the on-chain MultiAssetDelegation staking contract.
Delegate to an operator and choose a blueprint selection mode:
- All: you are exposed to all blueprints the operator participates in.
- Fixed: you choose which blueprint IDs you accept exposure to.
Optionally apply a lock multiplier (1–6 months) to boost reward share.

TNT Deposit Incentives (`RewardVaults`)

TNT incentives are paid from RewardVaults:

One vault per staking asset (native, TNT, etc.).
Governance sets a deposit cap and whether the vault is active.
Rewards are paid in TNT from a pre-funded InflationPool (no minting).
Delegator share is based on principal × lock multiplier and the operator’s commission setting.

Service Fee Revenue (`ServiceFeeDistributor`)

When customers pay for a service, the protocol splits fees and routes the staker portion per operator to ServiceFeeDistributor. From there, fees are distributed to delegators who staked with that operator based on:

Delegated amount (and optional lock multiplier)
Blueprint selection (All vs Fixed)
Optional per-asset commitments and USD weighting (if a price oracle is configured)
Optional streaming over a service’s TTL (for streamed payments)

Exposure-Based Protocol Rewards (`InflationPool`)

If enabled, InflationPool can allocate a staker budget in TNT based on service exposure. Exposure is computed at distribution time using ServiceFeeDistributor and optional USD pricing.

The keeper calls InflationPool.distributeEpochWithServices(serviceIds).
TNT is routed into ServiceFeeDistributor and claimed there (same flow as service fees).

Risks

Slashing reduces the withdrawable value of operator positions using share/exchange-rate accounting.
Use Fixed blueprint selection if you want to scope exposure to specific blueprints.

User Stories

Maya the staker

She delegates 1,000 wstETH to a trusted operator in Fixed mode for two blueprints she understands.
She earns USDC fees from services on those blueprints and optional TNT incentives from the staking vault.
When the operator stops serving a blueprint, she removes it from her fixed list to reduce exposure.

Lee the integrator

He builds a dashboard that shows stakers their estimated service-fee rewards.
He reads scores and pending rewards from ServiceFeeDistributor, and vault info from RewardVaults.
