Bundlr's fee is dynamic and depends on several parameters.
Fees are computed as follows:
bundlr_fee(X = number of bytes) = arweave_cost(max(X, 10000)) * conversion_rate("AR", currency) * global_multiplier * oracle_fee
arweave_costis cost of storing
Xnumber of bytes on Arweave using linear pricing (i.e. ignoring minimum chunk size). e.g. if
arweave_cost(256KB) = $2.56then
arweave_cost(1KB) = $0.01
conversion_rateis the conversion rate between AR and some other currency (e.g. MATIC). This allows users to pay the same fees in different currencies.
global_multiplieris a multiplier applied to all transactions which can be seen as a “profit margin”.
oracle_feeis a risk multiplier which accounts for cost of treasury management and asset volatility.
Due to a ~3.5x increase in the base cost to store on Arweave (arweave_cost) brought about by the 2.6 hardfork, we are temporarily subsidizing 75% of all upload costs. We expect the cost to stabilize as new miners enter the network and will discontinue subsidizing when the base cost drops.
