Stream type
{
    from: address'matic',
    to: address'matic',
    value: int256,
    op: string,
    transaction: {
        gasUsed: int256,
        gasLimit: int256,
        gasPrice: int256,

Code Samples
This simple code will monitor native (MATIC) withdrawals and deposits on a single address.
stream _
from PolygonTransfers
where @to == MATIC.address("0xAddress") 
|| @from == MATIC.address("0xAddress") 
​
process
  emit { @from, @to, @value }
end
​
This code will send a notification to a user when more than 1 MATIC were withdrawn from an address.
stream _
from PolygonTransfers
where @from == MATIC.address("0xAddress") 
​
process
  if @value >= 1000000000000000000 then
    emit { @from, @to, @value }
  end
  
end
PolygonErc20Transfers
PolygonErc20Transfers Stream represents all supported Polygon based ERC20 Token transfers with positive (> 0) value.
Stream type
{
    from: address'matic',
    to: address'matic',
    value: int256,
    token: {
        verified: boolean,
        name: string,
        symbol: string,
        contract: address'matic',
        decimals: int256
    }, 
    transaction: {
        gasUsed: int256,
        gasLimit: int256,
        gasPrice: int256,
        fee: int256,
        origin: address'matic',
        nonce: int256,
        index: int256,
        hash: string,
        blockHash: string
    },
    block: {
        number: int256,
        hash: string,
        parentHash: string,
        coinbase: address'matic',
        difficulty: int256,
        timestamp: int256,
        header: {
            gasUsed: int256,
            nonce: int256,
            sha3Uncles: string,

            mixHash: string,
            stateRoot: string,
            logsBloom: string,
            transactionsRoot: string,
            receiptsRoot: string
        },
        rewards: [
            {
                value: {
                    beneficiary: address'matic',
                    reward: int256
                }
            }
        ]
    }
}
Code Samples
This example will monitor every transfer of all tokens on one address
stream _
from PolygonErc20Transfers
where @from == MATIC.address("0xAddress")
|| @to == MATIC.address("0xAddress")
​
process
  let decimals = @token.decimals
  let symbol = @token.symbol
  emit { @from, @to, @value, decimals, symbol }
end
​
To monitor transfers of only one ERC20 token on an address, you should add a condition like this
stream _
from PolygonErc20Transfers
where @from == MATIC.address("0xAddress")
|| @to == MATIC.address("0xAddress")
​
process
​
  let decimals = @token.decimals
  let symbol = @token.symbol
  
  if @token.symbol == "TEST" then
    emit { @from, @to, @value, decimals, symbol }
  end
  
end
