FAsset Operational Parameters#

This page lists the current values for the most important parameters of the FAssets system.

Each listed parameter links to its documentation when available. Otherwise, it includes a description of the purpose of the parameter.

Some of the values might be adjusted during the Beta phases.

Open Beta (Coston) Parameter Values#

Minting and Redeeming#

Parameter XRP BTC DOGE
Minting cap
Total amount of allowed FAssets in circulation. Once reached, no more FAssets can be minted until some are redeemed. This is intended as a security measure. In the final deployment this cap will be gradually increased and finally removed.
none none none
Lot size 20 XRP 0.0004 BTC 100 DOGE
Collateral reservation fee (CRF) 0.1% 0.1% 0.1%
Redemption fee 0.1% 0.1% 0.1%
Redemption default premium 10% 10% 10%
Redemption default premium source
Where does the premium come from when an agent fails to pay the redeemer on time?
If the vault CR > 1.1, from the agent's vault. Otherwise, from the agent's vault and the collateral pool.
From the vault From the vault From the vault

Minting and Redeeming Payment Times#

Parameter XRP BTC DOGE
Underlying blocks for payment
The number of underlying blocks during which the minter or agent can pay the underlying value.
500 10 50
Underlying seconds for payment
The minimum time allowed for an agent to pay for a redemption or a minter to pay for minting.
15 minutes 2 hours 50 minutes
Average block time
The average time between two successive blocks on the underlying chain.
2 seconds 10 minutes 1 minute
Time of proof availability
The amount of time that proofs of payment or nonpayment must be available on the Data Connector.
1 day 1 day 1 day
Amount of extra time per redemption
The extra amount of time per redemption granted to an agent when many redemption requests occur in a short period of time.
30 seconds 60 seconds 60 seconds

Collateral Ratios#

Parameter XRP BTC DOGE
Backing factor 100% 95% 100%
Vault collateral
 •  Supported types $USDC, $USDT, simulated $WETH $USDC, $USDT, simulated $WETH $USDC, $USDT, simulated $WETH
 •  Minimal CR 1.4 1.4 1.4
 •  Collateral call band CR 1.3 1.3 1.3

 •  Minimal CR 2.0 2.0 2.0
 •  Collateral call band CR 1.9 1.9 1.9
 •  Safety CR 2.1 2.1 2.1
Minting pool holdings required
Minimum amount of pool tokens an agent must hold to be able to mint, as a percentage of the FAssets the agent is currently backing. Unlike pool and vault collateral ratios, if the agent's pool tokens go below this threshold, the agent does not go into liquidation, they just can't mint.

Maximum time an agent can remain in CCB before liquidation starts.
180 seconds 180 seconds 180 seconds
Liquidation premium

Liquidation source
Where do the funds come from to pay for liquidations.
 •  Liquidated value The agent's vault The agent's vault The agent's vault

Default Agent Settings#

These are the default values for the agent bot provided by the Flare foundation. Agents are free to adjust these settings as they see fit.

Parameter XRP BTC DOGE
Minting fee 0.25% 0.25% 0.25%
Pool share 40% 40% 40%
Minting CR
 •  Agent vault 1.6 1.6 1.6
 •  Collateral pool 2.3 2.3 2.3
Exit CR 2.3 2.3 2.3
Top-up CR 2.1 2.1 2.1
 •  Top-up discount 10% 10% 10%
Discount for agent self-close
In self-close exit, the pool token holder burns FAssets to increase pool CR enough to enable exit. Normally, the burned FAssets are redeemed in the normal redemption process. However, if the closed amount is less than 1 lot, or on explicit request, the agent buys the underlying assets (at a discounted FTSO price, to compensate the agent for possible price fluctuations) and pays the exiting token holder in vault collateral.

Rewarding#

Parameter XRP BTC DOGE
Challenger reward
After a successful challenge for an illegal operation, the agent goes into full liquidation and the challenger is paid this reward from the agent's vault.
300 $USD converted to vault collateral 300 $USD converted to vault collateral 300 $USD converted to vault collateral
Confirmation by others
If an agent or redeemer becomes unresponsive, anybody can confirm payments and non-payments some time after the request was made, and get a reward from the agent's vault.
 •  Minimum time 2 hours 4 hours 4 hours
 •  Reward 100 $USD converted to vault collateral 100 $USD converted to vault collateral 100 $USD converted to vault collateral
