Continuous Liquidity Pools (CLP) Deep Dive

The Continuous Liquidity Pool is the core innovation that allows THORChain to offer native cross-chain swaps without order books or wrapped assets. THORChain is increasingly described as a decentralized exchange (DEX); "liquidity protocol" remains accurate as mechanism context, but community-maintained docs are phasing it out as a product label.

What CLP Can Prove

CLP explains how THORChain prices a pool-based swap and why larger trades pay more slip/liquidity fee. THORChain pools external assets with RUNE; the formula links input size, depth, slip, fee, and output; shared settlement liquidity composes cross-chain routes. It does not prove that a current route is quoteable, cheap, available, or safe to execute.

How CLP Works

Every pool consists of RUNE paired with an external asset. THORChain docs describe slippage as the input size relative to pool depth, then use that slippage to derive the liquidity fee and final output:

slip = x / (X + x)
fee = (x^2 * Y) / (x + X)^2
output = (x * X * Y) / (x + X)^2

Where x is the input amount, X is the input-side pool depth, and Y is the output-side pool depth. The slip ratio is not itself the fee amount; the fee is denominated in the output asset.

Key Properties

• Quoteable through pool depth: CLP pricing can produce a quote across available pool depth, but execution still depends on current halt state, quote limits, outbound fees, recommended minimums, and refund rules.
• Progressive slippage: Larger trades pay proportionally more, making abrupt pool-price movement more expensive without guaranteeing LP protection or route safety.
• Separate LP action availability: Pool mechanics do not prove that LP adds, withdrawals, pool-specific deposits, or asymmetric withdrawals are currently open. Use the Liquidity Actions evidence guide before turning CLP mechanics into LP workflow claims.
• Historical single-sided products: Savers previously offered single-asset exposure, but official archived docs now mark Savers and Lending as deprecated.

If a swap limit is not met, the amount is below the recommended minimum, fees exceed the practical output, or a relevant chain/trading/signing control is halted, the transaction can be refunded or remain unavailable. Treat swap availability as live/current-only, not as a static property of the CLP formula.

Evidence Ladder

Use the narrowest evidence that matches the claim: official docs for mechanics, a fresh THORNode quote for a specific route, Network diagnostics for availability, labeled Midgard data for depth/APY, Liquidity Actions for LP operations, and the Streaming Swaps And Refunds ladder for refund causes. A formula alone is only partial evidence for a present-tense action.

Swap Lifecycle and Refunds

A normal swap journey starts before the CLP math is executed, but the full lifecycle — including quote, inbound, observation, execution, signing, and refund — is covered in depth in the Streaming Swaps And Refunds article. For operational triage of refunds and failed swaps, use that article before assigning a cause.

The CLP pricing formula — slip, fee, and output — runs at step 4 of that lifecycle, after quote validation and before outbound signing. Refunds can occur at any point when the swap cannot proceed, for reasons ranging from stale quotes to halted chains.

Comparison to Traditional AMMs

THORChain's CLP is a constant-function pool design with slip-based pricing, adapted to native cross-chain settlement through RUNE-paired pools. Its distinctive claim is the shared RUNE settlement graph and native-asset execution model, not an escape from constant-product-style pool economics. Current chain availability should be checked from live inbound-address and pool status, not from a hard-coded chain count.

A static formula is neither wallet guidance nor support diagnosis. Route execution, refunds, LP actions, depth/APY, and future outcomes all need the matching live evidence described above.

Common Misreadings

• "The slip ratio IS the fee." The slip ratio is the input size relative to pool depth. The fee is derived from that ratio but denominated in the output asset, not equal to the slip ratio itself.
• "LPs always earn from swap fees." Impermanent loss can exceed swap-fee income when relative asset prices move. LP returns depend on pool depth, price movement, fees and current availability. Impermanent loss protection (ILP) is historical: the official CLP documentation says it was removed for all liquidity providers. ADR-005, amended 7 November 2023, describes the permanent sunset. The older protection formulas on that page do not promise current coverage. This specific removal claim was source-checked on 2 October 2026; the article as a whole retains its existing review date.

Try A Single-Leg CLP Scenario

Use hypothetical model units to compare input size with input-side and output-side depth. The model shows slip ratio, liquidity fee and output as separate values. Source and version review belong to this lab alone; the article-wide review date is unchanged. Explain what the lab omits before using the separate live route check.
