Multi-Token Gas Protocol
On-chain protocol extension enabling registered PRC20 tokens as gas payment assets. Composed of Gas Token Registry, Swap Engine, and Gas Settlement; token conversion and miner fee settlement via NuaSwap.

01 · Definition
Protocol Definition
Multi-Token Gas Protocol extends the EVM native gas model from a single native token to a PRC20 token set. Payment path: Registry admission → Swap Engine execution → Settlement finalization.
Gas Token Registry: admission & state · Swap Engine: PRC20 → PANTA execution · NuaSwap: liquidity & quote source · Gas Settlement: miner fee deduction & revenue distribution
02 · Use Cases
Use Cases
The protocol spans gas token registration, transaction payment, swap execution, and validator revenue distribution.
01
Projects deploy PRC20/PANTA liquidity pools on NuaSwap and register with Registry
02
Transactions specify PRC20 as the gas payment asset at submission
03
Validators receive Gas Revenue in PANTA
04
Bridged assets may join the gas token set after pool deployment
05
Shares PRC20 payment abstraction layer with On-Chain AI Protocol
03 · Modules
Protocol Modules
02
NuaSwap Integration
NuaSwap liquidity pools as quote source; pool depth constrains swap capacity and slippage bounds
03
Swap Engine
Executes on-chain PRC20 → PANTA swap; input quote derived from NuaSwap pool state
04
Gas Settlement
PANTA miner fee deduction, validator revenue allocation, and on-chain final settlement
04 · NuaSwap
NuaSwap Swap Layer
Gas token quotes are derived from NuaSwap liquidity pools. Swap Engine executes PRC20 → PANTA conversion based on pool state; settlement unit is PANTA Miner Fee.
PRC20 Input → Pool Quote → Swap Execution → PANTA Output → Miner Fee Settlement
- Pool Quote: current swap ratio in the NuaSwap liquidity pool
- Swap Execution: Swap Engine completes PRC20 → PANTA at pool quote
- Miner Fee Settlement: gas settled to validators in PANTA
05 · Payment Path
Transaction Payment Path
At execution, the protocol reads NuaSwap pool quote for the selected PRC20, swaps to PANTA via Swap Engine, deducts Miner Fee, and updates state.
Select
Specify PRC20 gas payment asset
Quote
Read NuaSwap pool quote
Swap
Swap Engine executes PRC20 → PANTA
Execute
Deduct Miner Fee and broadcast transaction
Settle
Distribute Gas Revenue to validators
06 · Registry
Registry Admission
Gas Token Registry manages PRC20 tokens eligible for gas payment; admission requires a valid NuaSwap liquidity pool.
PRC20 standard compliance and contract security audit
NuaSwap token/PANTA liquidity pool established
Minimum pool depth and liquidity requirements
Governance review and dynamic rating adjustment
07 · Lifecycle
Protocol Lifecycle
Pool & Register
Project adds NuaSwap pool for PRC20 and registers in Gas Token Registry
Quote Binding
Gas token bound to NuaSwap liquidity pool for quote derivation
Swap Execution
Swap Engine executes PRC20 → PANTA at pool quote
Broadcast
Deduct Miner Fee in PANTA and complete transaction or contract call
Finalization
Settlement module distributes Gas Revenue to validators
08 · Settlement
Settlement & Revenue Distribution
After PRC20 is swapped to PANTA via Swap Engine, Settlement executes Miner Fee deduction and Gas Revenue distribution.
PRC20_PAY → NUASWAP_SWAP → PANTA → MINER_FEE → VALIDATOR_REWARD → STATE_UPDATE
- Miners/validators: receive gas revenue in PANTA
- Protocol treasury: ecosystem incentives and governance funds (per protocol params)
- On-chain transparency: all settlement records auditable and traceable

10 · Features
Protocol Features
Open Registration
Compliant PRC20 admitted by Registry joins the gas token set
On-Chain Swap
Swap Engine completes atomic PRC20 → PANTA within the transaction path
Pool Quote
Gas token quotes derived from NuaSwap liquidity pool state
Multi-Layer Validation
Signature verification, nonce replay protection, and gas limit bounds
Bridged Assets
Bridged assets may register as gas tokens after pool deployment
PRC20 Payment
Transaction gas payable directly in registered PRC20
11 · Ecosystem
Cross-Protocol Relation
Gas Fee and AI Service Fee are metered and settled independently at the protocol layer; both use the PRC20 payment abstraction.
