Did Sauron suspect that the Ring would be destroyed? I think this would allow for much more applications where devs can figure out how nft collections are used (as pure investments, as loan collateral, being swapped for assets, etc.). So if this could be included in the output for /nft/0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d/transfers then I wouldnt have to do all these extra calls and I think lots of people will be able to use this. Thanks for contributing an answer to Ethereum Stack Exchange! JavaScript front end for Odin Project book library database. Why does the capacitance value of an MLCC (capacitor) increase after heating? Time between connecting flights in Norway. I want to ask how u decode the input/log are SWAP?
