# Stake Funds For Gas
The exchange ratio for gas is:
The value changes by the TOP tokens staked in system.
An ordinary account can't obtain gas more than 200,000 Tgas(on-chain governance parameter) in 24-hour. This roughly equates to 800 transactions.
A contract account can't obtain more than 10,000,000 Tgas (on-chain governance parameter) in a 24-hour. This equates to 40,000 transactions or 4s of CPUT time.
Maximum gas of an account can exchange(24h)=Maximum gas of an account can obtain(24h)-free gas(24h)

Please use command 'topio querytx' to query transaction status later on!!!
Execute topio querytx to query the transaction, when the consensus final status is "success", execute topio chain queryAccount to query the account's total gas and available gas, if they have corresponding changes, then the stake is a success.
- Failed
Transaction hash: 0xf7d951259032e9797d91a6a7d9590a845673da03a54e54fa776c2fec85afec06
Please use command 'topio querytx' to query transaction status later on!!!
Execute topio querytx to query the transaction, when the consensus final status is "failure", then failed to stake for gas.
# Withdraw Funds For Gas
After initiating the withdrawn, you have to wait 24 hours and send a transaction (not a query) before the TOP tokens are received.
Withdraw rules:
According to the ratio of withdrawn TOP to total staked TOP, the corresponding gas is released from the account. For example, staked 1200 TOP exchanges 1500Tgas and withdraw 400 TOP, which accounts for 1/3 of the total staked TOP. Accordingly, 1/3 of the total gas is released, that is, 500 Tgas.
