gem install rubysolLet's try the PublicMintER20 Contract...
contracts/public_mint_erc20.rb:
class PublicMintERC20 < ERC20
storage maxSupply: UInt,
perMintLimit: UInt
sig [String, String, UInt, UInt, UInt]
def constructor(
name:,
symbol:,
maxSupply:,
perMintLimit:,
decimals:
)
super( name: name,
symbol: symbol,
decimals: decimals)
@maxSupply = maxSupply
@perMintLimit = perMintLimit
end
sig [UInt]
def mint( amount: )
assert(amount > 0, 'Amount must be positive')
assert(amount <= @perMintLimit, 'Exceeded mint limit')
assert( @totalSupply + amount <= @maxSupply, 'Exceeded max supply')
_mint(to: msg.sender, amount: amount)
end
sig [Address, UInt]
def airdrop( to:, amount: )
assert(amount > 0, 'Amount must be positive')
assert(amount <= @perMintLimit, 'Exceeded mint limit')
assert(@totalSupply + amount <= @maxSupply, 'Exceeded max supply')
_mint(to: to, amount: amount)
end
endthat builds on the ERC20 (base) contract.
class PublicMintERC20 < ERC20
storage maxSupply: UInt,
perMintLimit: UInt
sig [String, String, UInt, UInt, UInt]
def constructor(
name:,
symbol:,
maxSupply:,
perMintLimit:,
decimals:
)
super( name: name,
symbol: symbol,
decimals: decimals)
@maxSupply = maxSupply
@perMintLimit = perMintLimit
end
sig [UInt]
def mint( amount: )
assert(amount > 0, 'Amount must be positive')
assert(amount <= @perMintLimit, 'Exceeded mint limit')
assert( @totalSupply + amount <= @maxSupply, 'Exceeded max supply')
_mint(to: msg.sender, amount: amount)
end
sig [Address, UInt]
def airdrop( to:, amount: )
assert(amount > 0, 'Amount must be positive')
assert(amount <= @perMintLimit, 'Exceeded mint limit')
assert(@totalSupply + amount <= @maxSupply, 'Exceeded max supply')
_mint(to: to, amount: amount)
end
endLet's go.
