Crate pallet_accumulate_and_forward 

Accumulate-and-Forward Pallet

Intercepts configurable token inflows (transaction fees, dust removal, coretime revenue) on system parachains and gathers them in a local accumulation account for periodic forwarding to a configurable destination.

Usage

• Fees: Use DealWithFeesSplit to split fees between accumulation and other handlers
• Burns/Revenue: Use the pallet as OnUnbalanced<CreditOf> handler (e.g., dust removal, coretime revenue) Note: Direct calls to pallet_balances::Pallet::burn() extrinsic are not redirected to the accumulation account — they still reduce total issuance directly.

Setup

The accumulation account must be pre-funded with at least the existential deposit. For new chains, include the account in the balances genesis config. For existing chains, fund it via a manual transfer.

If the accumulation account is not pre-funded, deposits below ED will be silently burned.

Total Issuance

Accumulated funds are burnt upon forwarding (reducing total_issuance here) and the same funds are minted at the destination when the sent message is received.
