Why does Saline matter?

Answering the question "Why use Saline" in short format:

• Similar capabilites of other networks
• Increased security (you don't forfeit custody - ever, there is no execution that can fail and lose your assets)
• Flexible and simple (intents make up mandates -> feature rich, grammatically simple, extremely powerful)

What can you build with it?

Better policies	Better services	Better... mandates?
Because the policies are on-chain, on the asset address themselves, they are superior to policies built at a wallet app or pre-transaction check level. They are also much easier to audit and compose.	Because any asset can be staked to secure off-chain computation, not just Ethereum (as with Eigenlayer), automated verifiable services are not only freed from protocol hacks like restaking but also enable Bitcoin, USDC or memecoin staking.	An on-chain fund can become a thing. The fund mandate can be a mandate: the assets that it is allowed to trade, the redemption rules, the high water mark… Capital calls have never been easier, as assets can remain with the LP until conditions are met for their transfer.

Mandates are universal

In Saline, mandates serve as the authoritative mechanism governing all interactions with assets. Unlike traditional blockchains, where asset movements are validated solely through cryptographic signatures—leaving the underlying intent opaque—Saline enforces all operations against a set of explicit, on-chain rules defined in a mandate.

These mandates are publicly visible, verifiable, and form the core of the Saline execution model. Every transaction is validated by checking whether the proposed action complies with the rules associated with the involved wallet(s). This validation process is part of consensus.

Because mandates are:

• Written in a high-level, human-readable DSL
• Stored and enforced on-chain
• Evaluated as part of the consensus-driven validation process

… they offer a deterministic, secure, and verifiable means of expressing complex logic—without relying on off-chain infrastructure or third-party wallet software.

Validation Guarantees

• Any transaction affecting a mandate-controlled address is subject to verification.
• Verification is non-optional and enforced at the protocol level.
• If a transaction does not conform to the associated mandate(s), it is rejected — analogous to signature failure in conventional blockchains.

This model eliminates the need for custodial wallet applications and external execution logic. All logic is embedded in the asset control layer itself. As a result, users retain full custodial control while gaining expressive, programmable behavior for their assets—natively, on-chain.
