For Yield Providers - Sundial Protocol

A Yield Provider is a traditional finance institution whose yield strategy is listed on the Yield Marketplace. This page explains the choice you make as a provider and what a listing contains. To list, contact the team through the Sundial GitHub organization.

Choose a rail

A rail is the on-chain structure that holds depositors’ BTC for your program. You choose it. Depositors don’t see it.

	Dawn	Solstice
Best for	Fixed-term, fixed-rate programs	Open-ended, pooled strategies
Deposits	Each deposit is its own escrow	Pooled in one vault
Your obligation	Claim each escrow, then distribute principal plus yield before the deadline	Report the position, and keep the redemption buffer funded
Depositor holds	A timelocked position	A receipt token
Status	Public testnet	In development

If you already have your own on-chain presence, you can list without using a rail.

What a listing contains

A listing has a provider record and one or more programs. Provider

Field	Meaning
`name`	Your display name

Program

Field	Meaning
`name`, `description`	What depositors see
`expected_yield_bps`	Expected yield in basis points. `500` is 5%.
`min_lock_ms`	Minimum lock period in milliseconds. `86400000` is one day.
`distribution_type`	When yield is paid. `FINAL` pays once, at the end.
`program_vault_address`	The Bitcoin address that receives claimed funds
`provider_pubkey_hex`	Your 33-byte compressed public key, in hex. It goes into each depositor’s Escrow script.

Your responsibilities on Dawn

Claim before the deadline. You sweep each Escrow output with your key.
Distribute before the deadline. You send principal plus the agreed yield to the depositor’s Timelock address.
Keep your key safe. provider_pubkey_hex is embedded in every depositor’s script. The matching private key is the only thing that can claim.

Steps 1 and 2 are your obligations under the agreement you sign with each depositor. See how Dawn works.

Building the transactions

The btc-locker SDK builds the claim and distribution transactions.
